2008-04-28mm: introduce pte_special pte bitNick Piggin
s390 for one, cannot implement VM_MIXEDMAP with pfn_valid, due to their memory model (which is more dynamic than most). Instead, they had proposed to implement it with an additional path through vm_normal_page(), using a bit in the pte to determine whether or not the page should be refcounted: vm_normal_page() { ... if (unlikely(vma->vm_flags & (VM_PFNMAP|VM_MIXEDMAP))) { if (vma->vm_flags & VM_MIXEDMAP) { #ifdef s390 if (!mixedmap_refcount_pte(pte)) return NULL; #else if (!pfn_valid(pfn)) return NULL; #endif goto out; } ... } This is fine, however if we are allowed to use a bit in the pte to determine refcountedness, we can use that to _completely_ replace all the vma based schemes. So instead of adding more cases to the already complex vma-based scheme, we can have a clearly seperate and simple pte-based scheme (and get slightly better code generation in the process): vm_normal_page() { #ifdef s390 if (!mixedmap_refcount_pte(pte)) return NULL; return pte_page(pte); #else ... #endif } And finally, we may rather make this concept usable by any architecture rather than making it s390 only, so implement a new type of pte state for this. Unfortunately the old vma based code must stay, because some architectures may not be able to spare pte bits. This makes vm_normal_page a little bit more ugly than we would like, but the 2 cases are clearly seperate. So introduce a pte_special pte state, and use it in mm/memory.c. It is currently a noop for all architectures, so this doesn't actually result in any compiled code changes to mm/memory.o. BTW: I haven't put vm_normal_page() into arch code as-per an earlier suggestion. The reason is that, regardless of where vm_normal_page is actually implemented, the *abstraction* is still exactly the same. Also, while it depends on whether the architecture has pte_special or not, that is the only two possible cases, and it really isn't an arch specific function -- the role of the arch code should be to provide primitive functions and accessors with which to build the core code; pte_special does that. We do not want architectures to know or care about vm_normal_page itself, and we definitely don't want them being able to invent something new there out of sight of mm/ code. If we made vm_normal_page an arch function, then we have to make vm_insert_mixed (next patch) an arch function too. So I don't think moving it to arch code fundamentally improves any abstractions, while it does practically make the code more difficult to follow, for both mm and arch developers, and easier to misuse.

2008-04-22[MTD] [NAND] support for pxa3xxeric miao
This is preliminary since: 1. It supports only _one_ chip select at the moment. As there is no existing platforms available using two chip selects of the NAND controller, it shall really not include code for supporting the 2nd chip select for now, as such code cannot be verified. 2. It resorts to the default and simpliest memory based badblock table 3. Only limited types of nand flash are currently supported. Most PXA3xx processors come with on-chip NAND flash dies, so there isn't much flexibility for other types of NAND. 4. The NAND controller should be configured to detect the device's ID, thus making it difficult to use nand_scan_ident() to assist the detection process (though it's not impossible) TODO: fix all the above limitations of cuz :-) Signed-off-by: eric miao <eric.miao@marvell.com> Cc: Sergey Podstavin <spodstavin@ru.mvista.com> Signed-off-by: David Woodhouse <dwmw2@infradead.org>

2008-04-19[ARM] pxa: allow dynamic enable/disable of GPIO wakeup for pxa{25x,27x}eric miao
Changes include: 1. rename MFP_LPM_WAKEUP_ENABLE into MFP_LPM_CAN_WAKEUP to indicate the board capability of this pin to wakeup the system 2. add gpio_set_wake() and keypad_set_wake() to allow dynamically enable/disable wakeup from GPIOs and keypad GPIO * these functions are currently kept in mfp-pxa2xx.c due to their dependency to the MFP configuration 3. pxa2xx_mfp_config() only gives early warning if MFP_LPM_CAN_WAKEUP is set on incorrect pins So that the GPIO's wakeup capability is now decided by the following: a) processor's capability: (only those GPIOs which have dedicated bits within PWER/PRER/PFER can wakeup the system), this is initialized by pxa{25x,27x}_init_mfp() b) board design decides: - whether the pin is designed to wakeup the system (some of the GPIOs are configured as other functions, which is not intended to be a wakeup source), by OR'ing the pin config with MFP_LPM_CAN_WAKEUP - which edge the pin is designed to wakeup the system, this may depends on external peripherals/connections, which is totally board specific; this is indicated by MFP_LPM_EDGE_* c) the corresponding device's (most likely the gpio_keys.c) wakeup attribute: Signed-off-by: eric miao <eric.miao@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-04-19[ARM] pxa: add MFP-alike pin configuration support for pxa{25x, 27x}eric miao
Pin configuration on pxa{25x,27x} has now separated from generic GPIO into dedicated mfp-pxa2xx.c by this patch. The name "mfp" is borrowed from pxa3xx and is used here to alert the difference between the two concepts: pin configuration and generic GPIOs. A GPIO can be called a "GPIO" _only_ when the corresponding pin is configured so. A pin configuration on pxa{25x,27x} is composed of: - alternate function selection (or pin mux as commonly called) - low power state or sleep state - wakeup enabling from low power mode The following MFP_xxx bit definitions in mfp.h are re-used: - MFP_PIN(x) - MFP_AFx - MFP_LPM_DRIVE_{LOW, HIGH} - MFP_LPM_EDGE_* Selecting alternate function on pxa{25x, 27x} involves configuration of GPIO direction register GPDRx, so a new bit and MFP_DIR_{IN, OUT} are introduced. And pin configurations are defined by the following two macros: - MFP_CFG_IN : for input alternate functions - MFP_CFG_OUT : for output alternate functions Every configuration should provide a low power state if it configured as output using MFP_CFG_OUT(). As a general guideline, the low power state should be decided to minimize the overall power dissipation. As an example, it is better to drive the pin as high level in low power mode if the GPIO is configured as an active low chip select. Pins configured as GPIO are defined by MFP_CFG_IN(). This is to avoid side effects when it is firstly configured as output. The actual direction of the GPIO is configured by gpio_direction_{input, output} Wakeup enabling on pxa{25x, 27x} is actually GPIO based wakeup, thus the device based enable_irq_wake() mechanism is not applicable here. E.g. invoking enable_irq_wake() with a GPIO IRQ as in the following code to enable OTG wakeup is by no means portable and intuitive, and it is valid _only_ when GPIO35 is configured as USB_P2_1: enable_irq_wake( gpio_to_irq(35) ); To make things worse, not every GPIO is able to wakeup the system. Only a small number of them can, on either rising or falling edge, or when level is high (for keypad GPIOs). Thus, another new bit is introduced to indicate that the GPIO will wakeup the system: - MFP_LPM_WAKEUP_ENABLE The following macros can be used in platform code, and be OR'ed to the GPIO configuration to enable its wakeup: - WAKEUP_ON_EDGE_{RISE, FALL, BOTH} - WAKEUP_ON_LEVEL_HIGH The WAKEUP_ON_LEVEL_HIGH is used for keypad GPIOs _only_, there is no edge settings for those GPIOs. These WAKEUP_ON_* flags OR'ed on wrong GPIOs will be ignored in case that platform code author is careless enough. The tradeoff here is that the wakeup source is fully determined by the platform configuration, instead of enable_irq_wake().

2008-04-19[ARM] pxa: separate GPIOs and their mode definitions to pxa2xx-gpio.heric miao
two reasons: 1. GPIO namings and their mode definitions are conceptually not part of the PXA register definitions 2. this is actually a temporary move in the transition of PXA2xx to use MFP-alike APIs (as what PXA3xx is now doing), so that legacy code will still work and new code can be added in step by step Signed-off-by: eric miao <eric.miao@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-04-19[ARM] pxa: integrate low IRQ chip (ICIP) and high IRQ chip (ICIP2) into oneeric miao
This makes the code better organized and simplified a bit. The change will lose a bit of performance when performing IRQ ack/mask/unmask,but that's not too much after checking the result binary. This patch also removes the ugly #ifdef CONFIG_PXA27x .. #endif by carefully not to access those pxa{27x,3xx} specific registers, this is done by keeping an internal IRQ number variable. The pxa-regs.h is also modified so registers for IRQ > PXA_IRQ(31) are made public even if CONFIG_PXA{27x,3xx} isn't defined (for pxa25x's sake) The incorrect assumption in the original code that internal irq starts from 0 is also corrected by comparing with PXA_IRQ(0). "struct sys_device" for the IRQ are reduced into one single device on pxa{27x,3xx}. Signed-off-by: eric miao <eric.miao@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
