[U-Boot] [PATCH V2 0/4] configs: make keystone2 config to start using arm_v7_common header

[Nishanth Menon]

For legacy reasons, keystone2 had kind of stayed completely seperated
from the rest of the TI SoC families. This makes no sense since there
are a lot of common definitions that can be reused between all SoC
configuration allowing for a consistent user experience.

So make keystone2 follow the rest of the TI SoCs based on OMAP
architecture as well.

Test log: K2H:  http://pastebin.ubuntu.com/11889270/ (using https://patchwork.ozlabs.org/patch/440665/)
I have no other platform to verify on.

Series based on master 4905dfc65d9a Merge branch 'master' of git://git.denx.de/u-boot-spi


Changes in V2:
	- got rid of the bogus CONFIG_LINUX_BOOT_PARAM_ADDR
	- few additional config cleanups based on off line comment from Tom Rini.

[U-Boot] [PATCH V2 1/4] configs: split ti_armv7_common into a omap generic header

[Nishanth Menon]

TI armv7 based SoCs are based on two architectures - one based on OMAP
generation architecture and others based on Keystone architecture.

Many of the options are architecture specific, however a lot are common
with v7 architecture. So, step 1 will be to move out OMAP specific stuff
from ti_armv7_common into a ti_armv7_omap.h header which is then used
by all the relevant architecture headers.

Why do we need MMC options in common? Only keystone device that uses MMC 
is Galileo. This should stay in individual device specific or
board specific config file.

Same here..

I believe currently keystone doesn't use GPIO, but this may change.
Probably remove this as well for now and add it when GPIO is supported 
on K2.

Including the common ti_armv7_common.h for keystone also add duplication 
of the various addresses

#define DEFAULT_LINUX_BOOT_ENV \
	"loadaddr=0x82000000\0" \
	"kernel_addr_r=0x82000000\0" \
	"fdtaddr=0x88000000\0" \
	"fdt_addr_r=0x88000000\0" \
	"rdaddr=0x88080000\0" \
	"ramdisk_addr_r=0x88080000\0" \
	"bootm_size=0x10000000\0"

Some of these are also defined in keystone common file. The env scripts 
for keystone to be reworked to use the common variable above.

Rework the CONFIG_EXTRA_ENV_KS2_BOARD_SETTINGS to include common as well.

Did you do a test with env default -f -a with this to check if it 
continues to work for Keystone Linux boot.

I assume the one you have removed is already part of 
include/configs/ti_armv7_keystone2.h.

precisely why MMC is present in generic - lack of mmc is not consistent
in all ks2 devices as well - we can #undef if as necessary. I did miss
undefing it in patch #4 - I just did #undef CONFIG_SPL_MMC_SUPPORT

I can respin patch #4. with these added in.

patch #4:

+/* And no support for GPIO, yet.. */
+#undef CONFIG_SPL_GPIO_SUPPORT
+#undef CONFIG_CMD_GPIO


idea being to have as many common definitions as possible and undef the
ones we dont need as necessary. only thing i was careful here about was
to try and remove all OMAP specific defines out.

we need to cleanup all the variables  once we get the distro config
included in anyways... I had decided not to rock the apple cart too much
with this patch -> just the basic consolidation with as minimal changes
as necessary. inclusion of DEFAULT_LINUX_BOOT_ENV into keystone2.h can
be done as a follow on patch.

after the series: http://pastebin.ubuntu.com/11893531/
before the series: http://pastebin.ubuntu.com/11893576/
deltas:
bootdelay is 1 now
additional definitions:
arch=arm
soc=keystone    	
vendor=ti
cpu=armv7
board=ks2_evm
board_name=ks2_evm

will be great to get a tested by on that. Nothing else seems to have
changed.

arm_v7_common defines just "u-boot#" for all SoC and boards. So, we dont
need this.

for i in `git grep "^#define" include/configs/ti_armv7_keystone2.h|sed
-e "s/\s\s*/ /g"|cut -d ' ' -f2|sort|uniq`; do k=`git grep $i

Then started cleaning them up.

What do you mean by distro config? Could you explain?

Probably not this one. User would see both these variables and will 
cause confusion and should be fixed.

Sorry, this may be needed from the automation perspective. Also for 
backward compatibility for users. Would like to keep for K2.

include/config_distro* - both will eventually get integrated into
armv7_common.h to benefit all TI SoC platforms.

they are no variables, they are defines. they will eventually be fixed.
I am leery to make a huge jump on a single series. lets do consolidation
in small baby steps please.

as I have already shown in my reply - the status quo is being maintained
and we are one step closer to an common framework.

This has been beaten to death in the past as well (I think some 3/4
years ago.. i think it should be in the archives, just too lazy to dig
through multi-year old discussions)..

I will let Tom comment more here. My understanding is that the
convention followed by all other TI SoCs will imply not having custom
sys_prompt..


That said, custom sys_prompt is NOT a need from automation perspective -
we have all our boards in automation farm for years now with and without
custom boot prompt. board identification can be done in other ways.

Ok I see. But that doesn't mean we can accept duplicate env variables.
Do you see my point?

The defines finally create env variables on NAND or any other medium :)
So my comment stays.

Ok. If this happens soon (within a month) I am fine with this. 
Otherwise, this could go under the radar and cause maintenance issue.

 From a users perspective as well, it is good to know which board I am 
working with when I work with multiple boards. Not sure what is the 
argument not to have a board specific prompt at u-boot level. Definitely 
like to hear from Tom.

Yes.  But mainline U-Boot doesn't need to support N versions of Y
distros.  That's the point behind the generic distro work.  And this
means that yes, a lot of the addr_X things keystone sets get dropped
later on.  For better or worse there isn't overlap in names between
these two choices so the old scripts will still use the old values and
the new scripts the new values.

We can drop a bunch of addr_* stuff if you prefer :)

As Nishanth said, we beat this topic to death a long time back.  Generic
prompt is what we do.
