Anurag Dutta <a-dutta@ti.com> says: Hi All, In u-boot, hbmc is broken and has been removed from j7200 configs. This series re-enables the hbmc driver and introduces a series of hyperflash boot fixes. At present, in u-boot, the parent device (fss) gets registered as a syscon device. This is done because the MMIO mux driver in u-boot did not support the mux functionality when the parent device is not a syscon. In this series, we make relevant changes in the hbmc driver as well as dts' so that we can use the reg-mux driver for selecting the appropriate state of the mux.
