Subject: [PATCH] util/mkimage: Use grub_host_to_target32() instead of
|
||
|
|
grub_cpu_to_le32()
|
||
|
|
|
||
|
|
The latter doesn't take into account the target image endianness. There is
|
||
|
|
a grub_cpu_to_le32_compile_time() but no compile time variant for function
|
||
|
|
grub_host_to_target32(). So, let's keep using the other one for this case.
