more excruciatingly pedantic queries ... what is the best practice
for header files under include/configs including common header files
also in that same directory. i give you:
$ git grep zynq-common.h
bitmain_antminer_s9.h:#include
syzygy_hub.h: * See zynq-common.h for Zynq common configs
i'm rewriting a bunch of u-boot tutorial pages (publicly available
if anyone wants to read them), and i want to clarify the proper
location to put configuration content -- a defconfig file versus a
header file -- knowing that the trend lately has been to move content
into defconfig files where
e:
embedded.c
fw_printenv
fw_printenv_unstripped
it is obviously not removed by "make distclean". is this deliberate?

i'm doing this in the context of building for ARM with a linaro
toolchain, but i'm sure it's equally valid in the context of a native
build.
i'm trying to generate the same output as u-boot.map, but more
condensed and with each symbol associated with its original source
file (if that's even
and so on to come up with the final .config.
if someone already did that once upon a time, that'd be great, but
i'm going to guess i'm on my own here. thoughts?
