2008-06-30[ARM] Orion: make PCI handling code deal with Cardbus slotsLennert Buytenhek
The Cardbus connector does not have an IDSEL signal, and Cardbus cards are always the intended target of configuration transactions on their local PCI bus. This means that if the Orion's PCI bus signals are hooked up to a Cardbus slot, the same set of PCI functions will will appear 31 times, for each of the PCI device IDs 1-31 (ID 0 is the host bridge). This patch adds a function to the Orion PCI handling code that board support code can call to enable Cardbus mode. When Cardbus mode is enabled, configuration transactions on the PCI local bus are only allowed to PCI IDs 0 (host bridge) and 1 (cardbus device).

Kurobox Pro/Linkstation Pro devices use a microcontroller connected to UART1. As most of the communication with this microcontroller is done from userland (power button detection, fan speed ...), the setup file has to make UART1 available from userland.

2008-06-22[ARM] Feroceon: L2 cache supportLennert Buytenhek
This patch adds support for the unified Feroceon L2 cache controller as found in e.g. the Marvell Kirkwood and Marvell Discovery Duo families of ARM SoCs. Note that: - Page table walks are outer uncacheable on Kirkwood and Discovery Duo, since the ARMv5 spec provides no way to indicate outer cacheability of page table walks (specifying it in TTBR[4:3] is an ARMv6+ feature). This requires adding L2 cache clean instructions to proc-feroceon.S (dcache_clean_area(), set_pte()) as well as to tlbflush.h ({flush,clean}_pmd_entry()). The latter case is handled by defining a new TLB type (TLB_FEROCEON) which is almost identical to the v4wbi one but provides a TLB_L2CLEAN_FR flag. - The Feroceon L2 cache controller supports L2 range (i.e. 'clean L2 range by MVA' and 'invalidate L2 range by MVA') operations, and this patch uses those range operations for all Linux outer cache operations, as they are faster than the regular per-line operations. L2 range operations are not interruptible on this hardware, which avoids potential livelock issues, but can be bad for interrupt latency, so there is a compile-time tunable (MAX_RANGE_SIZE) which allows you to select the maximum range size to operate on at once. (Valid range is between one cache line and one 4KiB page, and must be a multiple of the line size.) Signed-off-by: Lennert Buytenhek <buytenh@marvell.com>

2008-06-22[ARM] Orion: add a separate BRIDGE_INT_TIMER1_CLR defineKe Wei
Some Feroceon-based SoCs have an MBUS bridge interrupt controller that requires writing a one instead of a zero to clear edge interrupt sources such as timer expiry. This patch adds a new BRIDGE_INT_TIMER1_CLR define, which platform code can set to either ~BRIDGE_INT_TIMER1 (write-zero-to-clear) or BRIDGE_INT_TIMER1 (write-one-to-clear) depending on the platform.

2008-06-22[ARM] Feroceon: speed up flushing of the entire cacheNicolas Pitre
Flushing the L1 D cache with a test/clean/invalidate loop is very easy in software, but it is not the quickest way of doing it, as there is a lot of overhead involved in re-scanning the cache from the beginning every time we hit a dirty line. This patch makes proc-feroceon.S use "clean+invalidate by set/way" loops according to possible cache configuration of Feroceon CPUs (either direct-mapped or 4-way set associative).

2008-06-22[ARM] Orion: avoid setting ->force_phy_addrLennert Buytenhek
The mv643xx_eth platform data field ->force_phy_addr only needs to be set if the passed-in ->phy_addr field is zero (to distinguish the case of not having specified a phy address (force_phy_addr = 0) from the case where a phy address of zero needs to be used (force_phy_addr = 1.)) Also, the ->force_phy_addr field will hopefully disappear in a future mv643xx_eth reorganisation. Therefore, this patch deletes the ->force_phy_addr field initialiser from all Orion board code.

2008-06-22[ARM] Orion: remove error printks in ->map_irq() implementationsLennert Buytenhek
If all PCI devices are working as expected, the error printks in the various implementations of ->map_irq() doesn't really provide any useful info. And if something is not working as expected, turning on pci=debug gives you more useful information than the printk calls in ->map_irq(), since the former also tells you which devices _did_ get IRQs successfully assigned. Therefore, delete these printks entirely. Spotted by Russell King. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com> Acked-by: Russell King <linux@arm.linux.org.uk>

2008-06-22[ARM] Orion: move setting up PCIe WA window into PCIe setup pathLennert Buytenhek
It makes no sense to do PCIe WA window setup in the individual board support files while the decision whether or not to use the PCIe WA access method is made in a different place, in the PCIe support code. This patch moves the configuration of a PCIe WA window from the individual Orion board support files to the central Orion PCIe support code.

2008-06-22[ARM] Orion: move EHCI/I2C/UART peripheral init into board codeLennert Buytenhek
This patch moves initialisation of EHCI/I2C/UART platform devices from the common orion5x_init() into the board support code. The rationale behind this is that only the board support code knows whether certain peripherals have been brought out on the board, and not initialising peripherals that haven't been brought out is desirable for example: - to reduce user confusion (e.g. seeing both 'eth0' and 'eth1' appear while there is only one ethernet port on the board); and - to allow for future power savings (peripherals that have not been brought out can be clock gated off entirely).

2008-06-22[ARM] Orion: top-level IRQs are level-triggeredLennert Buytenhek
Make it clear that Orion top-level IRQs are level-triggered. This means that we don't need an ->ack() handler, or at least, we don't need the ->ack() handler (or the acking part of the ->mask_ack() handler) to actually do anything. Given that, we might as well point our ->mask_ack() handler at the ->mask() handler instead of providing a dummy ->ack() handler, since providing a ->mask_ack() handler on level IRQ sources will prevent ->ack() from ever being called.

2008-06-22[ARM] Orion: DRAM mapping granularity is 64KiB, not 16MiBLennert Buytenhek
The DRAM base address and size fields in the CPU's MBUS bridge have 64KiB granularity, instead of the currently used 16MiB. Since all of the currently supported MBUS peripherals support 64KiB granularity as well, this patch changes the Orion address map code to stop rounding base addresses down and sizes up to multiples of 16MiB.

2008-06-22[ARM] Orion: make window setup a little more safeLennert Buytenhek
Currently, Orion window setup uses hardcoded window indexes for each of the boot/cs0/cs1/cs2/PCIe WA windows. The static window allocation used can clash if board support code will ever attempt to configure both a dev2 and a PCIe WA window, as both of those use CPU mbus window #7 at present. This patch keeps track of the last used window, and opens subsequently requested windows sequentially, starting from 4. (Windows 0-3 are used as MEM/IO windows for the PCI/PCIe buses.)

2008-06-22[ARM] cache align destination pointer when copying memory for some processorsNicolas Pitre
The implementation for memory copy functions on ARM had a (disabled) provision for aligning the source pointer before loading registers with data. Turns out that aligning the _destination_ pointer is much more useful, as the read side is already sufficiently helped with the use of preload. So this changes the definition of the CALGN() macro to target the destination pointer instead, and turns it on for Feroceon processors where the gain is very noticeable.
