* | nommu: ptrace supportPaul Brook2009-07-242-1/+15
| | | | | | | | | | | | | | | | | | The patch below adds ARM ptrace functions to get the process load address. This is required for useful userspace debugging on mmuless systems. These values are obtained by reading magic offsets with PTRACE_PEEKUSR, as on other nommu targets. I picked arbitrary large values for the offsets. Signed-off-by: Paul Brook <paul@codesourcery.com>

* | Thumb-2: Make the uImage entry an odd numberCatalin Marinas2009-07-241-1/+8
| | | | | | | | | | | | | | This allows U-Boot to branch to the kernel in Thumb-2 mode via "mov pc, lr". Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
* | Thumb-2: Pass a Thumb-2 address to the secondary CPUs to jump toCatalin Marinas2009-07-241-12/+6
| | | | | | | | | | | | | | This patch sets bit 0 in the startup address passed to the secondary CPUs so that they branch into Thumb-2 mode. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
* | Thumb-2: Add support for loadable modulesCatalin Marinas2009-07-243-0/+62
| | | | | | | | | | | | | | | | | | | | Modules compiled to Thumb-2 have two additional relocations needing to be resolved at load time, R_ARM_THM_CALL and R_ARM_THM_JUMP24, for BL and B.W instructions. The maximum Thumb-2 addressing range is +/-2^24 (+/-16MB) therefore the MODULES_VADDR macro in asm/memory.h is set to (MODULES_END - 8MB) for the Thumb-2 compiled kernel.

* | Thumb-2: Add macros for the unified assembler syntaxCatalin Marinas2009-07-243-1/+130
| | | | | | | | | | | | | | | | This patch adds various C and assembler macros that help with using the unified assembler syntax for compiling files to either ARM or Thumb-2 modes. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
* | Thumb-2: Add some .align statements to the .S filesCatalin Marinas2009-07-245-0/+13
|/ | | | | | | | Since the Thumb-2 instructions can be 16-bit wide, data in the .text sections may not be aligned to a 32-bit word and this leads to unaligned exceptions. This patch does not affect the ARM code generation. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>

| | | | | | | | | | | | | | | | | | | | Removed the LBD support that isn't of any use right now at least, then remove remnants of the TCM config flags that somehow crept in by mistake (not yet merged patch for 2.6.32) and then the usual defconfig noise from updated menus.

This is perhaps not the optimal setting but setting it to 0 makes the system suspend and never come back again (all IRQ sources masked off).

| | * ARM: add support for the EET board, based on the i.MX31 pcm037 moduleGuennadi Liakhovetski2009-06-235-6/+283
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The "EET" variant of the pcm037 board has an OLED display, using a S6E63D6 display controller on the first SPI interface, using GPIO57 as a chip-select for it. S6E63D6 is initialised in the boot-loader, so we only have to take care of the LCD. EET also adds several buttons and LEDs on GPIOs. This patch adds a "pcm037_variant=" kernel command line parameter to specify at boot-time which board the kernel is running on, default is "pcm970", specify "eet" for the EET board.

Maintainers for: alpha, ia64 and m68k, please have a look, your arch code is funny. The header magic is a bit odd, but similar to the KERNEL_DS one, CPP waits with expanding these macros until the INIT_THREAD_INFO macro itself is expanded, which is in arch/*/kernel/init_task.c where we've already included sched.h so we're good.
