Hello,
I'm using the HEAD of the master branch from git://git.denx.de/u-boot-x86.git
I want to build U-Boot as 64bit EFI payload.
According to docs/README.efi, I've done the following:
u-boot-x86> make qemu-x86_defconfig
u-boot-x86> make menuconfig
x86 architecture ---> Mainboard vendor ---> efi
x86 architecture ---> Mainboard model ---> efi
Library routines ---> [*] Support running U-Boot from EFI
Library routines ---> Select EFI mode to use ---> Support running as
an EFI payload
Library routines ---> EFI 32/64-bit selection ---> Produce a stub
for running with 64-bit EFI
Save as .config and Exit
u-boot-x86> make
Here it builds for a while, but eventually fails when reaching:
CC lib/efi/efi_stub.o
lib/efi/efi_stub.c: In function ‘get_codeseg32’:
lib/efi/efi_stub.c:188:30: error: ‘CONFIG_SYS_MONITOR_LEN’ undeclared
(first use in this function)
CONFIG_SYS_TEXT_BASE + CONFIG_SYS_MONITOR_LEN < limit
^
lib/efi/efi_stub.c:188:30: note: each undeclared identifier is
reported only once for each function it appears in

scripts/Makefile.build:422: recipe for target 'lib/efi' failed
make[1]: *** [lib/efi] Error 2
Makefile:1206: recipe for target 'lib' failed
make: *** [lib] Error 2
I tried also with the 32bit stub and I get a different (linker) error:
arch/x86/cpu/start.o: In function `_start':
/home/igor/dev/tmp/bbb/u-boot-x86/arch/x86/cpu/start.S:87: undefined

Any idea of what mistakes I am making?
