common: Drop asm/global_data.h from common header

2021-02-02T20:33:42+00:00

Move this out of the common header and include it only where needed.  In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly.   Finally, we have a few
cases where we did not need to include  at all, so
remove that include.

microblaze: Enable GCC garbage collector for full U-Boot

2020-11-20T09:42:53+00:00

GCC's garbage collector works for Microblaze for quite a long time but none
has enabled it.
The same change has be done for example by commit fac4790491f6 ("arc:
Eliminate unused code and data with GCC's garbage collector").

Before:
   text	   data	    bss	    dec	    hex	filename
 588760	  33592	  39192	 661544	  a1828	u-boot

After:
   text	   data	    bss	    dec	    hex	filename
 504504	  32164	  38608	 575276	  8c72c	u-boot

Which saves almost 15% of memory footprint.

Also group symbols/functions to proper section.

arch: Move NEEDS_MANUAL_RELOC symbol to Kconfig

2020-11-04T15:13:44+00:00

CONFIG_NEEDS_MANUAL_RELOC macro was out of Kconfig. Move it there to be
able to use compile-time checks to reduce the number of build paths.

Fixes: f9a882438966 ("dm: core: Convert #ifdef to if() in root.c") for Microblaze

xilinx: Merge together BOOT_SCRIPT_OFFSET between MB and ARM

There is no reason not to use commong Kconfig by Microblaze too.

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

2020-10-27T07:01:36+00:00

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

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

2020-10-27T07:01:33+00:00

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.

microblaze: Add support for little/big endian in/out api's

2020-09-23T08:31:40+00:00

Add read/write memory utilities for 16 and 32 bits. Add these
api's for both little and big endian systems similar to arm
architecture.

efi_loader: use CONFIG_STACK_SIZE in the UEFI sub-system

2020-08-01T09:58:23+00:00

The Kconfig symbol CONFIG_STACK_SIZE is used both by ARM and Microblaze
with the same meaning. Move it to menu 'General setup' so that we can use
it for all architectures.

Use the value of CONFIG_STACK_SIZE instead of a hard coded 16 MiB value for
reserving memory in the UEFI sub-system.
