omap: headers: Create headers necessary for compile under mach-omap1 and mach-omap2
Create the headers needed for compiling under
mach-omap1/include/mach and mach-omap2/include/mach.
This was done with the following script:
#!/bin/bash
mach_files="clkdev.h gpio.h hardware.h io.h irqs.h memory.h \
smp.h system.h timex.h uncompress.h vmalloc.h"
omaps="mach-omap1 mach-omap2"
mach_dir_old="arch/arm/plat-omap/include/mach"
plat_dir_new="arch/arm/plat-omap/include/plat"
mkdir -p $plat_dir_new
git add $plat_dir_new
for dir in $omaps; do
mach_dir_new="arch/arm/$dir/include/mach"
for header in $mach_files; do
file="$mach_dir_new/$header"
if [ ! -f $file ]; then
echo -ne "/*\n * $file\n */\n\n#include <plat/$header>\n" > $file
git add $file
if [ ! -f $plat_dir_new/$header ]; then
git mv $mach_dir_old/$header $plat_dir_new/$header
fi
