Subject: Makefile: use $(shell ...) for determining file_size
X-Git-Tag: KARO-TXA5-2015-06-26~880
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=67b060b46b117375b489de2112c90c456552b654;p=karo-tx-uboot.git

Makefile: use $(shell ...) for determining file_size

file_size was being calculated using back-ticks but map_size uses
$(shell ...). Update the file_size calculation to use $(shell ...).

From: Jeroen Hofstee <jeroen@myspectrum.nl>

The binary_size_check target relies on stat -c %s
to return the size of u-boot.bin. This only works
with GNU stat though. Use wc instead.
