ARM: tegra: set CONFIG_SYS_MMC_MAX_DEVICE
If CONFIG_API is ever to be enabled on Tegra, this define must be set, since api/api_storage.c uses it. A couple of annoyting things about CONFIG_SYS_MMC_MAX_DEVICE 1) It isn't documented in README. The same is true for a lot of similar defines used by api_storage.c. 2) It doesn't represent MAX_DEVICE but rather NUM_DEVICES, since the valid values are 0..n-1 not 0..n. However, I this patch does not address those shortcomings. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com>
