This commit set CONFIG_HUSH_PARSER_2021 as the default to trigger the CI with
this parser.
Nonetheless, Some boards are not compatible with new 2021 hush parser:
1. rcar3_ulcb:
When built with CONFIG_HUSH_PARSER_2021, the u-boot.img file size
exceeds the 1MB file limit of 890 bytes:
aarch64: + rcar3_ulcb
+u-boot.img exceeds file size limit:
+ limit: 0x100000 bytes
+ actual: 0x10037a bytes
+ excess: 0x37a bytes
Some complementary work is then needed to use CONFIG_HUSH_PARSER_2021
for this
board.
As CONFIG_BOOTCOMMAND is quite simple for this board, I think we can
gain some
bytes by deactivating hush features like if and loop.
2. the keymile (i.e. VENDOR_KM) family:
This boards used set_local_var() to store some variables as local shell.
They then used get_local_var() to retrieve the variables values.
Sadly, this two functions do not exist with CONFIG_HUSH_PARSER_2021.
A patch was proposed to use environment variables rather than local
variables
but it does not tackle the problem, so complementary work is needed to
make
this boards use CONFIG_HUSH_PARSER_2021 [1].
