Hi all,
The mainline has switched to Kconfig.
Please make sure to use "make <board>_defconfig" instead of "make <board>_config".
[1] Board Configuration
make <board_name>_defconfig[2] Modify configuration
make config, make menuconfig, make nconfig, ... etc.
For SPL, make spl/config, make spl/menuconfig, make spl/nconfig, ... etc.
I'm a bit confused here, a single "make" will build both the SPL + the regular u-boot binary, so why 2 separate menuconfig commands for them ?
To be a bit more specific, currently for sunxi for some boards (the ones most used by devs) we have both Foo_defconfig and Foo_FEL_defconfig with the latter one being identical to the first one, except that it not only defines SPL (all our builds use SPL) but also SPL_FEL, this changes some compile time settings as well as leads to using a different linker script for the SPL. The end result is a SPL binary which can be loaded through the "FEL" allwinner usb firmware loading / update mechanism, rather then written to a sdcard as our regular builds.
Rather then doubling the amount of defconfigs we have to allow using FEL on any sunxi board, I would like to remove the Foo_FEL_defconfig files and make it possible to do a FEL build by doing something like this:
make Foo_defconfig make menuconfig <select FEL> make
I was planning on taking a shot at this, but the different make menuconfig and make spl/menuconfigs have me somewhat confused (I've a decent knowledge of Kconfig from my kernel work).
Perhaps you can give me some hints on how I can best implement the above ?
Thanks & Regards,
Hans
