2005-07-27[PATCH] cpm_uart: use DPRAM for early consoleMarcelo Tosatti
m8xx_cpm_hostalloc() can't rely on using the coherent DMA allocator early on boot because the VM is not fully up yet. Change it to use the on-board DPRAM instead. The current code relies on the "bootmem_page" allocated by m8xx_cpm_reset(), which must be killed. This is done in v2.4 but has never been forward ported to v2.6.

2005-07-27[PATCH] serial: MRi MRI-PCIDS1 dual port serial cardDavid Ranson
Add support for the MRi PCIDS1 dual port serial card. This card is a little controversial since it is the subject of a PCI vendor/device ID clash. (See http://www.ussg.iu.edu/hypermail/linux/kernel/0303.1/0516.html). I have for now just used the hex ID 0x950a. The divisor was part calculated part iterated, so may not be exactly correct (but works for me at all settings between 300 - 115300 bps).

This patch adds the Freescale MPC86xADS board support. The supported devices are SMC UART and 10Mbit ethernet on SCC1. The manual for the board says that it "is compatible with the MPC8xxFADS for software point of view". That's why this patch extends FADS instead of introducing a new platform. FEC is not supported as the "combined FCC/FEC ethernet driver" driver by Pantelis Antoniou should replace the current FEC driver.

2005-06-21[PATCH] ioc4: PCI bus speed detectionBrent Casavant
Several hardware features of SGI's IOC4 I/O controller chip require timing-related driver calculations dependent upon the PCI bus speed.

2005-06-21[PATCH] ioc4: Core driver rewriteBrent Casavant
This series of patches reworks the configuration and internal structure of the SGI IOC4 I/O controller device drivers. These changes are motivated by several factors: - The IOC4 chip PCI resources are of mixed use between functions (i.e. multiple functions are handled in the same address range, sometimes within the same register), muddling resource ownership and initialization issues. Centralizing this ownership in a core driver is desirable. - The IOC4 chip implements multiple functions (serial, IDE, others not yet implemented in the mainline kernel) but is not a multifunction PCI device. In order to properly handle device addition and removal as well as module insertion and deletion, an intermediary IOC4-specific driver layer is needed to handle these operations cleanly. - All IOC4 drivers are currently enabled by a single CONFIG value. As not all systems need all IOC4 functions, it is desireable to enable these drivers independently. - The current IOC4 core driver will trigger loading of all function-level drivers, as it makes direct calls to them. This situation should be reversed (i.e. function-level drivers cause loading of core driver) in order to maintain a clear and least-surprise driver loading model. - IOC4 hardware design necessitates some driver-level dependency on the PCI bus clock speed. Current code assumes a 66MHz bus, but the speed should be autodetected and appropriate compensation taken. This patch series effects the above changes by a newly and better designed IOC4 core driver with which the function-level drivers can register and deregister themselves upon module insertion/removal. By tracking these modules, device addition/removal is also handled properly. PCI resource management and ownership issues are centralized in this core driver, and IOC4-wide configuration actions such as bus speed detection are also handled in this core driver. This patch: The SGI IOC4 I/O controller chip implements multiple functions, though it is not a multi-function PCI device. Additionally, various PCI resources of the IOC4 are shared by multiple hardware functions, and thus resource ownership by driver is not clearly delineated. Due to the current driver design, all core and subordinate drivers must be loaded, or none, which is undesirable if not all IOC4 hardware features are being used. This patch reorganizes the IOC4 drivers so that the core driver provides a subdriver registration service. Through appropriate callbacks the subdrivers can now handle device addition and removal, as well as module insertion and deletion (though the IOC4 IDE driver requires further work before module deletion will work). The core driver now takes care of allocating PCI resources and data which must be shared between subdrivers, to clearly delineate module ownership of these items.
