In arch/arm/mach-mvebu/dram.c we always include axp's xor.h for common
XOR definitions, regardless whether we compile for axp or a38x.
But the declaration of this function has a different signature in axp's
xor.h from the one used in a38x' implementation - one parameter is u64
instead of u32. This can result in wrong argument's being passed to that
function on a38x with no one the wiser.
I discovered this when building U-Boot for Turris Omnia with LTO. The
compiler complains about the different signatures being thrown into the
same linking process:
axp/xor.h:67:5: warning: type of ‘mv_xor_mem_init’ does not match
original declaration [-Wlto-type-mismatch]
67 | int mv_xor_mem_init(u32 chan, u32 start_ptr, u32 block_size,
| ^
a38x/xor.c:165:5: note: type mismatch in parameter 3
165 | int mv_xor_mem_init(u32 chan, u32 start_ptr, unsigned long long
| ^
a38x/xor.c:165:5: note: type ‘long long unsigned int’ should match
type ‘u32’
Fix this by changing the type of the block_size argument in the axp's
implementation and header file to the one used in a38x (and upstream
mv-ddr-marvell).
