Subject: Add some missing endian conversions in fdt_support.c
X-Git-Tag: v2011.12-rc1~221^2^2~1
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=de16606ae3445c3822720487178ecf7fbdd0c378;p=oweals%2Fu-boot.git

Add some missing endian conversions in fdt_support.c

Some functions in fdt_support.c use fdt_getprop to read 32 bit values out of
the device tree, but then use them directly without doing any endian
conversion. Because they check for a value that doesn't actually appear in
practice, the functions continued to work even though they're incorrect.
This change adds the missing conversions.
