This serie is the beginning of MPC8xx migration to DM model.
I didn't get any feedback on this serie. I don't feel totally confortable as
it is my first implementation of DM and also the first time powerpc uses DT
for U-boot.
I'd rather someone look at it.
One thing I'm noticing: Are you setting up pre-relocation malloc? Since MPC8xx
is another old powerpc platform, I suspect that the start.S doesn't do it, and
DM needs it to function correctly.
Yes, I did it with the following patch:
https://patchwork.ozlabs.org/patch/886980/
Best regards

Maybe you can model the case of MPC8xx similarly to the ones for MPC83xx and
MPC85xx (those are pretty similar):
dbcb2c0e2ba28 ("powerpc: mpc83xx: Enable pre-relocation malloc")
50689461205e0 ("powerpc: mpc85xx: Enable pre-relocation malloc for MPC85xx")
Thanks
Christophe
Best regards,
Mario
It applies on top of the serie "[v4] Powerpc: mpc8xx: cleanup before
migration to DM model"
Christophe Leroy (6):
board: MCR3000: Activate CONFIG_DM and CONFIG_OF_CONTROL
drivers: watchdog: add a DM driver for the MPC8xx watchdog
board: MCR3000: use new DM watchdog
drivers: serial: migrate mpc8xx to DM
board: MCR3000: migrate to DM_SERIAL
drivers: serial: get rid of non DM mpc8xx driver
Change since initial RFC:
Migrated serial driver in addition
Few changes on the watchdog
