Bernhard Nortmann 320e0570e6 sunxi: FEL - Add the ability to recognize and auto-import uEnv-style data ... The patch converts one of the "reserved" fields in the sunxi SPL header to a fel_uEnv_length entry. When booting over USB ("FEL mode"), this enables the sunxi-fel utility to pass the string length of uEnv.txt compatible data; at the same time requesting that this data be imported into the U-Boot environment. If parse_spl_header() in the sunxi board.c encounters a non-zero value in this header field, it will therefore call himport_r() to merge the string (lines) passed via FEL into the default settings. Environment vars can be changed this way even before U-Boot will attempt to autoboot - specifically, this also allows overriding "bootcmd". With fel_script_addr set and a zero fel_uEnv_length, U-Boot is safe to assume that data in .scr format (a mkimage-type script) was passed at fel_script_addr, and will handle it using the existing mechanism ("bootcmd_fel").
