Fix board init code to respect the C runtime environment

2016-01-14T02:05:17Z

board_init_f_mem() alters the C runtime environment's stack it is actually already using. This is not a valid behaviour within a C runtime environment. Split board_init_f_mem into C functions which do not alter their own stack and always behave properly with respect to their C runtime environment. Signed-off-by: Albert ARIBAUD Acked-by: Thomas Chou

nios2: fix cached mode in clearing the BSS

2015-11-06T01:14:12Z

As the generic board runs in cached mode, it should not use "stwio" which bypass the cache. Signed-off-by: Thomas Chou Reviewed-by: Chin Liang See

nios2: remove CONFIG_SYS_INIT_SP macro

2015-11-06T01:14:12Z

Remove CONFIG_SYS_INIT_SP macro, as the initial stack is set to below the u-boot code. Signed-off-by: Thomas Chou Reviewed-by: Marek Vasut Reviewed-by: Chin Liang See

nios2: set default cache configuration in start.S

2015-10-22T23:37:20Z

Set default icache and dcache configuration for start.S. We want to remove the CONFIG_SYS_{I,D}CACHE_SIZE... configuration macros. As we are just barely starting from reset, there is no luxury of device tree. We will set some maximum cache configuration so that it will work for most configurations. This is used only in this start.S. The speed penalty is only once here. After start up, during board initialization, cpu information will be extracted from device tree. Then cache flush operations will have correct cache configurations. Signed-off-by: Thomas Chou Acked-by: Marek Vasut

nios2: call board_init_f_mem

2015-10-22T23:28:50Z

We will need CONFIG_SYS_MALLOC_F_LEN to use serial uclass. So we shall undefine CONFIG_SYS_GENERIC_GLOBAL_DATA, and call board_init_f_mem() to allocates early malloc() memory with size of CONFIG_SYS_MALLOC_F_LEN in board_f.c. Signed-off-by: Thomas Chou Reviewed-by: Marek Vasut

nios2: zap version_string

2015-10-22T23:28:50Z

There is a weak version_string[] at common/cmd_version.c . Remove the one in start.S. Signed-off-by: Thomas Chou Acked-by: Marek Vasut

nios2: zap dly_clks

The dly_clks() in start.S is no use after switching to generic timer. Remove it. Signed-off-by: Thomas Chou Acked-by: Marek Vasut
