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.

common: board_r: Drop arch-specific ifdefs around initr_trap

2021-01-15T19:36:12+00:00

In order to remove the arch-specific ifdefs around initr_trap, introduce
arch_initr_trap weak initcall. Implementations for ppc/m68k/mips have
been moved to arch//lib/traps.c

Default implementation is a nop stub.

mips: remove deprecated UNCACHED_SDRAM() macro

2020-07-18T12:23:25+00:00

This macro only served as a wrapper for CKSEG1ADDR() with an
exception for CONFIG_TB0229. CONFIG_TB0229 doesn't exist, thus
use CKSEG1ADDR() directly.

This also prepares for an upcoming asm header sync with Linux.

mips: refactor disabling of caches

2020-07-18T12:23:25+00:00

Logically this code belongs to cache_init.S.

If a complex SoC needs to replace the generic cache init,
mips_cache_disable() can now be called from custom start.S files.

mips: add KSEG1 wrapper for change_k0_cca

2020-07-18T12:23:25+00:00

change_k0_cca() is called multiple times. Move the code for
changing to KSEG1 to a macro to avoid code duplication.

Also fix missing change to KSEG1 when changing to CONF_CM_CACHABLE_COW.

mips: cache: Make invalidate_dcache_range() weak to enable overwrite

2020-07-18T12:23:25+00:00

This patch adds __weak to invalidate_dcache_range() in lib/cache.c. This
makes it possible to overwrite this function by a platforms specific
version, which will be done for Octeon.

This patch enables the usage of CONFIG_MIPS_L2_CACHE without
CONFIG_MIPS_CM, which is what is needed for the newly added Octeon
platform.
