This works only with CONFIG_SUPPORT_RAW_INITRD undefined.

Otherwise you get:

image.c: In function 'boot_get_ramdisk':
image.c:1000: error: expected expression before 'char'
image.c:1001: error: 'end' undeclared (first use in this function)
image.c:1001: error: (Each undeclared identifier is reported only once
image.c:1001: error: for each function it appears in.)


You need braces to start a new block.

Best regards,

Wolfgang Denk
