Convert these boards to use a text environment. For the boards check, the only differences are extra spaces after the semicolons in 'dfu_alt_info_ram' and 'partitions', both of which are permitted. Add in the special boot command for old kernels, dropping the unnecessary and confusing hex prefixes. Signed-off-by: Simon Glass <sjg@chromium.org>
