possibly embarrassing myself here, but i just ran across this in
edb93xx.c, which looks ... weird, a mixture of "EGPIO" and "EPGIO"
toward the end of that source file:
... snip ...
int board_mmc_init(bd_t *bis)
{
struct gpio_regs *regs = (struct gpio_regs *)GPIO_BASE;
ep93xx_set_epgio(CONFIG_MMC_SPI_CS_EPGIO);
ep93xx_dir_epgio_out(CONFIG_MMC_SPI_CS_EPGIO);
#ifdef CONFIG_MMC_SPI_POWER_EGPIO
ep93xx_dir_epgio_out(CONFIG_MMC_SPI_POWER_EGPIO);
ep93xx_set_epgio(CONFIG_MMC_SPI_POWER_EGPIO);
#elif defined(CONFIG_MMC_SPI_NPOWER_EGPIO)
ep93xx_dir_epgio_out(CONFIG_MMC_SPI_NPOWER_EGPIO);
ep93xx_clear_epgio(CONFIG_MMC_SPI_NPOWER_EGPIO);
#endif
... snip ...
is it just me, or does anyone else find that odd? all occurrences of
the string "epgio" are entirely contained within that single source
file:
$ grep -ri EPGIO *

board/cirrus/edb93xx/edb93xx.c: struct mmc *mmc = mmc_spi_init(0,
CONFIG_MMC_SPI_CS_EPGIO,
$
am i just being an idiot in not knowing that that means?
