microblaze: start.S: Use board_init_f_alloc/init in early init

2020-10-27T07:01:36Z

Implement early init by calling generic board_init_f_alloc_reserve and board_init_f_init_reserve functions: * drop SYS_MALLOC_F_LEN related code, as allocation and gd->malloc_base assignment are taken care of by the generic functions * drop _gd logic Cc: Michal Simek Signed-off-by: Ovidiu Panait

microblaze: start.S: Factor out exception setup code to __setup_exceptions

2020-10-27T07:01:33Z

Currently, the exceptions setup code is duplicated in pre-relocation and post-relocation init. Factor out this code to __setup_exceptions asm routine to get rid of the duplication. __setup_exceptions is called with a relocation offset parameter (r5) which is set to zero for pre-reloc init and gd->reloc_off for post-reloc exception setup.

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini

microblaze: spl: configure SYS_MALLOC_F_LEN independently for SPL and full U-Boot

2017-07-27T12:59:03Z

Some platforms have very limited SRAM to run SPL code, so there may not be the same amount space for a malloc pool before relocation in the SPL stage as the normal U-Boot stage. Make SPL and (the full) U-Boot stage use independent SYS_MALLOC_F_LEN, so the size of pre-relocation malloc pool can be configured memory space independently.

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

microblaze: Add a TODO to call board_init_f_mem()

2015-10-24T17:50:37Z

This C function should be used to do the early memory layout and init. This is beyond my powers, so just add a TODO for the maintainer. Signed-off-by: Simon Glass Acked-by: Michal Simek

microblaze: spl: Do not call mem_malloc_init and use early alloc

2015-02-09T14:13:12Z

This patch has some parts connected together: - Use _gd in bss section which is automatically cleared Location at SPL_MALLOC_END wasn't cleared at all - Use MALLOC_F_LEN(early alloc) instead of FULL MALLOC (mem_malloc_init is not called at all) - Simplify malloc and stack init. At the end of SPL addr is malloc area and below is stack Signed-off-by: Michal Simek
