Add configuration file for mini u-boot configuration which runs on a smaller footprint from on chip memory(OCM). This configuration has required CONFIG's enabled to support octal spi flash and uses DCC terminal for console output. Add required dts for octal spi flash mini u-boot configuration.
Signed-off-by: Ashok Reddy Soma ashok.reddy.soma@amd.com ---
Changes in v3: - Add dts files for octal flash mini u-boot. - Add below configs to fix compilation error. CONFIG_HAS_CUSTOM_SYS_INIT_SP_ADDR=y CONFIG_CUSTOM_SYS_INIT_SP_ADDR=0xFFFE0000
Changes in v2: - Run savedefconfig and updated mini config for ospi to align with latest Kconfig layout
