Subject: Fix IHEX firmware generation/loading
X-Git-Tag: v2.6.27-rc2~62^2~1
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=85ebd00334099fd5d296bcae74a66c943d46686d;p=linux-2.6-omap-h63xx.git

Fix IHEX firmware generation/loading

Fix both the IHEX firmware generation (len field always null, and EOF
marker a byte too short) and loading (struct ihex_binrec needs to be
packed to reflect the on-disk structure).
