| | * ARM: Auto calculate ZRELADDR and provide option for exceptionsEric Miao2010-07-123-10/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As long as the zImage is placed within the 128MB range from the start of memory, ZRELADDR (Address where the decompressed kernel will be placed, usually == PHYS_OFFSET + TEXT_OFFSET) can be determined at run-time by masking PC with 0xf80000000. Running through all the Makefile.boot, all those zreladdr-y addresses == 0x[0-f][08]00_0000 + TEXT_OFFSET can be determined at run-time. Option CONFIG_AUTO_ZRELADDR and CONFIG_ZRELADDR are introduced, CONFIG_ZRELADDR _must_ be explicitly specified if: - ((zreladdr-y - TEXT_OFFSET) & ~0xf8000000) != 0, which means masking PC with 0xf8000000 will result in an incorrect address. Currently this is only a problem on u300. - or the assumption of the zImage being loaded by the bootloader within the first 128MB of RAM is incorrect - or when ZBOOT_ROM is used, where the above assumption is usually wrong.

| * | ARM: Fix decompressor's kernel size estimation for ROM=yRussell King2010-02-262-27/+26
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 2552fc2 changed the way the decompressor decides if it is safe to decompress the kernel directly to its final location. Unfortunately, it took the top of the compressed data as being the stack pointer, which it is for ROM=n cases. However, for ROM=y, the stack pointer is not relevant, and results in the wrong answer. Fix this by explicitly storing the end of the biggybacked data in the decompressor, and use that to calculate the compressed image size.

The problem is that local data generates GOTOFF relocations, which means we can't relocate the data relative to the text segment. Global data, on the other hand, goes through the GOT, and can be relocated anywhere. Unfortunately, with the new decompressors, this presents a problem since they declare static data within functions, and this leads to stack overflow. Fix this by separating out the decompressor code into a separate file, and removing 'static' from BSS data in misc.c. Also, discard the .data section - this means that should we end up with read/write initialized data, the decompressor will fail to link and the problem will be obvious.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace the use of CROSS_COMPILE to select a customized installkernel script with the possibility to set INSTALLKERNEL to select a custom installkernel script when running make: make INSTALLKERNEL=arm-installkernel install With this patch we are now more consistent across different architectures - they did not all support use of CROSS_COMPILE. The use of CROSS_COMPILE was a hack as this really belongs to gcc/binutils and the installkernel script does not change just because we change toolchain. The use of CROSS_COMPILE caused troubles with an upcoming patch that saves CROSS_COMPILE when a kernel is built - it would no longer be installable. [Thanks to Peter Z. for this hint] This patch undos what Ian did in commit: 0f8e2d62fa04441cd12c08ce521e84e5bd3f8a46 ("use ${CROSS_COMPILE}installkernel in arch/*/boot/install.sh") The patch has been lightly tested on x86 only - but all changes looks obvious.

"static inline strstarts(...)" becomes non-inline, and refers to the other string ops. The simplest workaround is to include asm/string.h.

* | [ARM] pxa: add base support for Marvell's PXA168 processor lineEric Miao2009-03-231-0/+12

It balances high computing and multimedia performance with low power consumption to support extended battery life, and includes a wealth of integrated peripherals to reduce overall BOM cost .... """ See http://www.marvell.com/featured/pxa168.jsp for more information. 1. Marvell Mohawk core is a hybrid of xscale3 and its own ARM core, there are many enhancements like instructions for flushing the whole D-cache, and so on 2. Clock reuses Russell's common clkdev, and added the basic support for UART1/2. 3. Devices are a bit different from the 'mach-pxa' way, the platform devices are now dynamically allocated only when necessary (i.e. when pxa_register_device() is called). Description for each device are stored in an array of 'struct pxa_device_desc'. Now that: a. this array of device description is marked with __initdata and can be freed up system is fully up b. which means board code has to add all needed devices early in his initializing function c. platform specific data can now be marked as __initdata since they are allocated and copied by platform_device_add_data() 4. only the basic UART1/2/3 are added, more devices will come later.

* | [ARM] 5383/2: unwind: Add core support for ARM stack unwindingCatalin Marinas2009-02-191-0/+5
|/ | | | | | | | | | | | | This patch adds the main functionality for parsing the stack unwinding information generated by the ARM EABI toolchains. The unwinding information consists of an index with a pair of words per function and a table with unwinding instructions.
