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].
