| | | * [ARM] 3958/1: add platform device (pxa2xx-udc)to ixp4xxMilan Svoboda2006-12-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Create include/asm-arm/arch-ixp4xx/udc.h and add platfrom device ixp4xx_udc_device into arch/arm/mach-ixp4xx/common.c. This allows us to use pxa2xx-udc on the ixp4xx platfrom. Both pxa2xx and ixp4xx use the same device controller.

| | | * [ARM] 3911/2: Simplify alloc_thread_info on ARMPaul Gortmaker2006-11-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove ARM local cache of 4 struct thread_info. Can cause oops under certain circumstances. Russell indicated the original optimization was required on older kernels to avoid thread starvation on memory fragmentation, but may no longer be required. I've updated the patch to 19rc4 and ensured no <config.h> dain-bramage slipped in this time (sorry about that). Original description follows: I was given some test results which pointed to an Oops in alloc_thread_info (happened 2x), and after looking at the code, I see that ARM has its own local cache of 4 struct thread_info. There wasn't any clear (to me) synchronization between the alloc_thread_info and the free_thread_info. I looked over the other arch, and they all simply allocate them on an as needed basis, so I simplified the ARM to do the same, based on the other arch (e.g. PPC) and the folks doing the testing have indicated that this fixed the oops.

* [PATCH] atmel_serial: Pass fixed register mappings through platform_dataHaavard Skinnemoen2006-10-04
| | | | | | | | | | | | | | | | | | | | | | | | | In order to initialize the serial console early, the atmel_serial driver had to do a hack where it compared the physical address of the port with an address known to be permanently mapped, and used it as a virtual address. This got around the limitation that ioremap() isn't always available when the console is being initalized. This patch removes that hack and replaces it with a new "regs" field in struct atmel_uart_data that the board-specific code can initialize to a fixed virtual mapping for platform devices where this is possible. It also initializes the DBGU's regs field with the address the driver used to check against. On AVR32, the "regs" field is initialized from the physical base address when this it can be accessed through a permanently 1:1 mapped segment, i.e. the P4 segment. If regs is NULL, the console initialization is delayed until the "real" driver is up and running and ioremap() can be used.
