[coreboot] [PATCH] Stop build if coreboot.rom.bootblock is larger than the area allocated to the bootblock

[Patrick Georgi]

Hi,

attached patch fixes an oversight in cbfstool related to bootblock handling.
With this patch, cbfstool reacts to a too large bootblock file by 
stopping with an error code. Before, it did "whatever" (besides printing 
a warning).
