Subject: tools/env: Fix environment size and CRC on 64-bit hosts
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=ea19527c209b0d97b532a8dc5bf28f2cdd016888;p=u-boot.git

tools/env: Fix environment size and CRC on 64-bit hosts

On architectures where 'long' is 64 bit, the u-boot environment
as seen by the fw_env tools was missing 4 bytes.
This patch fixes getenvsize(), and thus also ensures that the
environment's CRC32 checksum is calculated correctly.
