Subject: [PATCH] check-config: allow to complete build even with ad-hoc CONFIG
|
||||
options
|
||||
|
||||
Currently, the check-config.sh terminates the build when unknown
|
||||
ad-hoc options are detected. I think it is too much because we may
|
||||
want to patch config headers locally in a build/deployment project.
|
||||
|
||||
So, let's relax check-config.sh to just warn even if it detects
|
||||
options that are not in the whitelist. Instead, this check can be
|
||||
done at the end of build, along with other checks. It will catch
|
||||
more attention.
|
||||
|
||||
Even with this change, the Buildman tool catches new warnings,
|
||||
so Tom can give NACK to new ad-hoc options.

Compiling SPL is always tricky as it needs to fit limited resources.
|
||||
Fortunately in most cases there is no need to replace SPL or TPL while
|
||||
flashing a new firmware.
|
||||
|
||||
Compiling SPL for BCM4908 seems to fail with non-Broadcom toolchain:
|
||||
aarch64-openwrt-linux-musl-ld.bfd: u-boot-spl section `.u_boot_list' will not fit in region `.sram'
|
||||
aarch64-openwrt-linux-musl-ld.bfd: section .bss VMA [00000000822b9000,00000000822b93ef] overlaps section .u_boot_list VMA [00000000822b8f60,00000000822b9a87]
|
||||
aarch64-openwrt-linux-musl-ld.bfd: region `.sram' overflowed by 2696 bytes
|
||||
|
||||
It also requires hashtable.h which has to be generated using some
|
||||
Broadcom's custom perl script that isn't integrated as this point.
|
||||
|
||||
For now just disable SPL and use only last-stage U-Boot that must be
|
||||
shipped with every firmware.

Subject: [PATCH] Assume TPL support for ATF when compiling U-Boot without TPL
|
||||
MIME-Version: 1.0
|
||||
Content-Type: text/plain; charset=UTF-8
|
||||
Content-Transfer-Encoding: 8bit
|
||||
|
||||
Broadcom's U-Boot behaviour depends on compilation time check whether
|
||||
TPL was compiled with or without ATF support. There is no proper runtime
|
||||
check.
|
||||
|
||||
When compiling just U-Boot (without SPL & TPL) there is no way to tell
|
||||
if it's going to work with TPL with or without ATF support.
|
||||
|
||||
Modify code to blindly assume ATF support in TPL in such cases. It seems
|
||||
to be always true for Broadcom and we need some assumption as we don't
|
||||
deal with compiling SPL or TPL.
