We have 14 Config.lb files in the mainboard dir of our tree which all
contain exactly the same first section (comments and whitespace are
vastly different, but the code is identical):
Ron, you wrote that Config.lb can do include statements. I didn't find
any examples, but maybe I just looked at the wrong part of the code.
Tell me how to use the include statements and I'll refactor the section
below out of lots of boards.
--------------------------------------
##
## Compute the location and size of where this firmware image
## (coreboot plus bootloader) will live in the boot rom chip.
##
if USE_FAILOVER_IMAGE
default ROM_SECTION_SIZE = FAILOVER_SIZE
default ROM_SECTION_OFFSET = ( ROM_SIZE - FAILOVER_SIZE )
else
if USE_FALLBACK_IMAGE
default ROM_SECTION_SIZE = FALLBACK_SIZE
default ROM_SECTION_OFFSET = ( ROM_SIZE - FALLBACK_SIZE -
FAILOVER_SIZE )
else
default ROM_SECTION_SIZE = ( ROM_SIZE - FALLBACK_SIZE -
FAILOVER_SIZE )
default ROM_SECTION_OFFSET = 0
end
end
##
## Compute the start location and size size of
## The coreboot bootloader.
##
default PAYLOAD_SIZE = ( ROM_SECTION_SIZE - ROM_IMAGE_SIZE )
default CONFIG_ROM_PAYLOAD_START = (0xffffffff - ROM_SIZE +
ROM_SECTION_OFFSET + 1)
##
## Compute where this copy of coreboot will start in the boot rom
##
default _ROMBASE = ( CONFIG_ROM_PAYLOAD_START + PAYLOAD_SIZE )
##
## Compute a range of ROM that can cached to speed up coreboot,
## execution speed.
##
## XIP_ROM_SIZE must be a power of 2.
## XIP_ROM_BASE must be a multiple of XIP_ROM_SIZE
##
default XIP_ROM_SIZE=65536
#
if USE_FAILOVER_IMAGE
default XIP_ROM_BASE = ( _ROMBASE - XIP_ROM_SIZE + ROM_IMAGE_SIZE)
else
if USE_FALLBACK_IMAGE
default XIP_ROM_BASE = ( _ROMBASE - XIP_ROM_SIZE +
ROM_IMAGE_SIZE + FAILOVER_SIZE)
else
default XIP_ROM_BASE = ( _ROMBASE - XIP_ROM_SIZE + ROM_IMAGE_SIZE)
end
end
--------------------------------------
I'd like to place the section above in a generic
failover_size_calculation.lb file included by the respective targets.
Regards,
Carl-Daniel
