[PATCH 1/1] Added arm64 assembly for examples/api crt0

[Brunham, Kalen]

Hi Tom,

I'm using a defconfig that does not enable any of the configs listed on the default likes for config BLK (MMC, USB, SCSI, etc.), but I do have DM enabled. I cannot however enable BLK as CONFIG_BLK=y is ignored. My current hypothesis is that BLK is being forced to N by the select BLK in other Kconfig files, but I'm not sure. 

Here's the Kconfig for drivers/block:

config BLK
	bool # "Support block devices"
	depends on DM
	default y if MMC || USB || SCSI || NVME || IDE || AHCI || SATA
	default y if EFI_MEDIA || VIRTIO_BLK || PVBLOCK

My current flow is:
make mrproper
make socfpga_agilex5_defconfig
./scripts/kconfig/merge_config.sh -O ./ ./.config ../../my_uboot_config.txt

Here my_uboot_config.txt hsd:

CONFIG_MMC=n
CONFIG_USB=n
CONFIG_DM_MMC=n
CONFIG_SPL_DM_MMC=n
CONFIG_BLK=y
CONFIG_EFI_LOADER=y
CONFIG_CMD_BOOTEFI=y
CONFIG_EFI_LOADER=y
CONFIG_CMD_BOOTEFI_HELLO_COMPILE=y
CONFIG_CMD_BOOTEFI_HELLO=y

The only way I was able to get BLK set to Y was to add another default like || DM_SPI_FLASH, since I do enable SPI flash in this config. 

Thanks.

Can you please elaborate on what problem you see? Thanks.
