Subject: Create new fdt boardsetup command, fix bug parsing [] form of set values.
X-Git-Tag: v1.3.0-rc1~19^2~20^2~2^2~4
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=fd61e55dd8cb52ce3ff91b3917af26e24b6b0845;p=u-boot

Create new fdt boardsetup command, fix bug parsing [] form of set values.

Previously ft_board_setup() was called by fdt_chosen() which was not
really correctly structured.  This splits ft_board_setup() out by creating
a new fdt boardsetup command.

Fix a bug when parsing fdt set command values which have the square
bracket form [00 11 22 33] - the length was updated incorrectly in when
parsing that form.
