Subject: powerpc/ppc4xx: Make gdsys 405ep boards reset more generic
X-Git-Tag: v2012.07-rc1~149^2^2~5
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=6e9e6c36a6a52562edb3e3b93cbad33f9dfe5585;p=oweals%2Fu-boot.git

powerpc/ppc4xx: Make gdsys 405ep boards reset more generic

In order to add boards that have different hardware for fpga reset,
any 405ep gdsys board now provides these functions:

void gd405ep_init(void);
void gd405ep_set_fpga_reset(unsigned state);
void gd405ep_setup_hw(void);
int gd405ep_get_fpga_done(unsigned fpga);
