So, write enable the bit 19 should be 1 and write protected the bit 19 should be 0 at the Present State Register (0x24). According to the design of AST2600 EVB, the Write Protected pin is active high by default. To support it, introduces a new "sdhci_wp_inverted" property in ASPEED MACHINE State and set it true for AST2600 EVB and set "wp_inverted" property true of sdhci-generic model.
