svn commit: r293775 - head/sys/boot/uboot/lib

[Steven Hartland]

I think this breaks arm arches:
/usr/home/smh/freebsd/base/head1/sys/boot/uboot/lib/copy.c:103:24: 
error: use of undeclared identifier 'uintfptr_t'
                 subldr = rounddown2((uintfptr_t)_start, KERN_ALIGN);
                                      ^
/usr/home/smh/freebsd/base/head1/sys/boot/uboot/lib/../../../sys/param.h:295:28: 
note: expanded from macro 'rounddown2'
#define rounddown2(x, y) ((x)&(~((y)-1)))          /* if y is power of 
two */
