ARMv8: fix error in freeing stack frame

2017-10-08T20:19:56Z

relocate_code() allocates 32 bytes stack frame but only 16 bytes are freed before return. it will cause errors to possible previous frames and doesn't make relocate_code() look like a function. fix by freeing 32 bytes stack space Signed-off-by: zijun_hu Reviewed-by: Simon Glass

ARMv8: get new GD address from gd->new_gd directly

2017-10-08T20:19:56Z

the new GD address is calculated via board data BD currently it require the new GD area locates below BD tightly, so a strict constraint is imposed on memory layout which maybe make special platform unpleasant. fix it by getting new GD address from gd->new_gd directly.

env: Rename getenv/_f() to env_get()

2017-08-16T12:30:24Z

We are now using an env_ prefix for environment functions. Rename these two functions for consistency. Also add function comments in common.h. Quite a few places use getenv() in a condition context, provoking a warning from checkpatch. These are fixed up in this patch also. Suggested-by: Wolfgang Denk Signed-off-by: Simon Glass

env: Rename setenv() to env_set()

armv8: TPL_STACK will always be defined, so test CONFIG_TPL_NEEDS_SEPARATE_STACK

2017-08-13T15:12:35Z

Now that TPL_STACK has been moved off the whitelist (ok, I'm lying: the 'moving off the whitelist' part comes in once moveconfig runs... which will be a few commits down the line) and added to Kconfig, we need to test CONFIG_TPL_NEEDS_SEPARATE_STACK to see whether the value from TPL_STACK should be used or whether we try to inherit whatever SPL uses.

armv8: spl: Support separate stack for TPL

2017-08-13T15:12:21Z

To allow a TPL and SPL to run from different addresses/memories, we need to split setup of the TPL and SPL stacks. To do so, we introduce CONFIG_TPL_STACK (not listed in Kconfig) which can be used to override the initial stack pointer for TPL. To provide backward compatibility for existing boards, this is added as an optional configuration item and the normal search order (i.e. SPL_STACK, then SYS_STACK) apply if not defined.

The author of the commit discovered later on that this was already being done in cleanup_before_linux() on arch/arm/cpu/armv7m/cpu.c. This reverts commit 8f079cccb369995e46a2ab530d5d60b88c1e70bb. Signed-off-by: Tom Rini

ARM: provide a valid exception stack address for startup code

2017-06-12T12:38:40Z

Create exception stack in IRAM if available to facilitate debugging of pre-relocation code by catching exceptions rather than stopping dead. Signed-off-by: Lothar Waßmann
