arch: mips: Update initrd_start and initrd_end

2019-05-03T14:42:23+00:00

Microsemi SoC defines CONFIG_SYS_SDRAM_BASE to be 0x80000000, which
represents the start of kseg0 and represents a virtual address. Meaning
that the initrd_start and initrd_end point somewhere kseg0.
When these parameters are passed to linux kernel through DT
they are pointing somewhere in kseg0 which is a virtual address but linux
kernel expects the addresses to be physical addresses(in kuseg) because
it is converting the physical address to a virtual one.

Therefore update the uboot to pass the physical address of initrd_start
and initrd_end by converting them using the function virt_to_phys before
setting up the DT.

bootm: mips: Remove boot_reloc_ramdisk

2019-04-12T15:32:50+00:00

Remove the function boot_reloc_ramdisk in the file arch/mips/lib/bootm
because it is relocating again the ramdisk. The function do_bootm_states()
already relocates the ramdisk even if it is a legacy uImage or a FIT image.

The relocation in the function do_bootm_states() was introduce in the
commit c2e7e72bb9f0cb47d024997b381cb64786eb5402 ("bootm: relocate ramdisk
if CONFIG_SYS_BOOT_RAMDISK_HIGH set")

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

2018-05-07T13:34:12+00:00

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.

fdt: Implement weak arch_fixup_fdt()

2018-02-18T19:53:38+00:00

Only ARM and in some configs MIPS really implement arch_fixup_fdt().
Others just use the same boilerplate which is not good by itself,
but what's worse if we try to build with disabled CONFIG_CMD_BOOTM
and enabled CONFIG_OF_LIBFDT we'll hit an unknown symbol which was
apparently implemented in arch/xxx/lib/bootm.c.

Now with weak arch_fixup_fdt() right in image-fdt.c where it is
used we get both items highlighted above fixed.

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

2017-08-16T12:30:24+00:00

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.

MIPS: bootm: Fix broken boot_env_legacy codepath

2017-07-25T18:44:00+00:00

This patch fixes 2 bugs introduced by the following commit

2bb5b63 MIPS: bootm: rework and fix broken bootm code

The CONFIG_IS_ENABLED macro prepends 'CONFIG_' Hence, remove CONFIG_
from CONFIG_MIPS_BOOT_ENV_LEGACY usage.

Also, 2bb5b63 reworks bootm so that linux_env_legacy runs before
linux_cmdline_legacy. However, linux_env_legacy depends on
linux_cmdline_legacy running first as linux_cmdline_init initialilzes
linux_argp which linux_env_legacy later depends on during its
initialization.

Reorder the code so that linux_cmdline_legacy runs before
linux_env_legacy.

libfdt: replace ARCH_FIXUP_FDT with ARCH_FIXUP_FDT_MEMORY

2016-12-03T03:54:34+00:00

Commit e2f88dfd2d96 ("libfdt: Introduce new ARCH_FIXUP_FDT option")
allows us to skip memory setup of DTB, but a problem for ARM is that
spin_table_update_dt() and psci_update_dt() are skipped as well if
CONFIG_ARCH_FIXUP_FDT is disabled.

This commit allows us to skip only fdt_fixup_memory_banks() instead
of the whole of arch_fixup_fdt().  It will be useful when we want to
use a memory node from a kernel DTB as is, but need some fixups for
Spin-Table/PSCI.

MIPS: Use ram_top, not bi_memsize, in arch_lmb_reserve

2016-11-30T15:15:51+00:00

When calculating the region to reserve for the stack in
arch_lmb_reserve, make use of ram_top instead of adding bi_memsize to
CONFIG_SYS_SDRAM_BASE. This avoids overflow if the system has enough
memory to reach the end of the address space.

libfdt: Introduce new ARCH_FIXUP_FDT option

2016-08-01T01:37:08+00:00

Add new Kconfig option to disable arch_fixup_fdt() calls for cases where
U-Boot shouldn't update memory setup in DTB file.
One example of usage of this option is to boot OS with different memory
setup than U-Boot use.
