The EN25QH256A variant of the EN25QH256 doesn't initialize correctly from SFDP alone and only accesses memory below 8m (addr_width is 4 but read_opcode takes only 3 bytes). Set SNOR_F_4B_OPCODES if the flash chip variant was detected using hwcaps. The fix submitted upstream uses the PARSE_SFDP initializer that is not available in the kernel used with Openwrt.
