* arm: Keep track of the tlb size as well as its locationGabe Black2013-01-10-2/+4
| | | | | | | | | It may be necessary to know where the TLB area ends as well as where it starts. This allows board code to complete a secure memory erase without destroying the page tables. Signed-off-by: Gabe Black <gabeblack@google.com> Signed-off-by: Simon Glass <sjg@chromium.org>
* arm: move flush_dcache_all() to just before disable cacheArun Mankuzhi2013-01-10-1/+4
| | | | | | | | | | | | | | | | | | | In Cortex-A15 architecture, when we run cache invalidate the cache clean operation executes automatically. So if there are any dirty cache lines before disabling the L2 cache these will be synchronized with the main memory when invalidate_dcache_all() runs in the last part of U-boot The two functions after flush_dcache_all is using the stack. So this data will be on the cache. After disable when invalidate is called the data will be flushed from cache to memory. This corrupts the stack in invalida_dcache_all. So this change is required to avoid the u-boot hang. So flush has to be done just before clearing CR_C bit Signed-off-by: Arun Mankuzhi <arun.m@samsung.com> Signed-off-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Modified the arch-kirkwood header so KWGBE_PORT_SERIAL_CONTROL1_REG(x) returns the correct address. Originally calling KWGBE_PORT_SERIAL_CONTROL1_REG(1) returned the address for port 0 and vice versa. Doesn't have any knock on effects to the u-boot code as the only time they're used is to do the same function to both addresses Signed-off-by: Luke Lowrey <luke@chamsys.co.uk> Acked-by: Prafulla Wadaskar <Prafulla@marvell.com> Acked-by: Heiko Schocher <hs@denx.de>

| * | arm/km: remove duplicate codeValentin Longchamp2013-01-09-14/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes 2 small portions of board specific code that are duplicated with common ARM code and thus unnecessary. These 2 portions of code concern the mach id that is given by u-boot to the Linux kernel to identify the system's MACH. The first one was the possibility to change the MACH thanks to the 'mach_id' enviroment variable. This is possible thanks to the 'machid' env variable (see arch/arm/lib/bootm.c:boot_jump_linux()). The seconde one is the setting of the bi_arch_number. This is already done in arch/arm/lib/board.c:board_init_f() since km_arm.h does #define CONFIG_MACH_TYPE.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On kmcoge5un we faced some serious problems with the memory during temperature tests. Reason was that we overwrite some registers for memory settings which have to leave untouched. These where registers 0x20148 , 0x2014c and 0x20154. So writing these registers is prohibited and this patch removes them from all km related config files. Even if the problem was only seen on kmcoge5un.

This covers the code sequence from setting up the initial stack to calling into board_init_r(). Also, rewrite the C runtime setup and make functions board_init_*() and relocate_code() behave according to normal C semantics (no jumping across the C stack any more, etc). Some SPL targets had to be touched because they use start.S explicitly or for some reason; the relevant maintainers and custodians are cc:ed. Signed-off-by: Albert ARIBAUD <albert.u.boot@aribaud.net>

Also, even though the ROUND macro is already defined in common.h, the reason for redefining it in image.h is explained by Stefano Babic: "I will remark a previous comment - even if including common.h seems a good idea to avoid duplications, it makes tools like mkimage to depend on the selected board, because <board>_config must run. Even if this is not a problem for us u-boot developers, it becomes an issue when these tools are included in distros (like u-boot-tools in Ubuntu) and cannot be packaged."
