MIPS Malta's power off depends on PCI, PCI_QUIRKS, and

Shouldn't we also update the _defconfig files?
Sorry, in my last email, I forgot to reply to all. So I am now
resending this email.
In malta_defconfig, PCI and POWER_RESET_PIIX4_POWEROFF have already
been set and PCI_QUIRKS is also selected by FSL_PCI [=n].
So shutdown and reboot with malta_defconfig is working and there is no
need to update the malta_defconfig 🙂
Since the dependency is now enforced by Kconfig, the defconfig can
be simplified:

I understand from what you say that you update malta_defconfig manually ?
defconfigs shouldn't be updated manually.
Once you have the new .config you should use "make savedefconfig" then
replace your file by the newly generated defconfig file.

To do so, I just unset CONFIG_POWER_RESET and set it again in
menuconfig, then "make savedefconfig". The POWER_RESET part is simplified.
CONFIG_POWER_RESET=y
-CONFIG_POWER_RESET_PIIX4_POWEROFF=y
-CONFIG_POWER_RESET_SYSCON=y
However, I found that there's other changes in this new
malta_defconfig, for example
CONFIG_NLS_KOI8_U=m CONFIG_CRYPTO_CRYPTD=m -CONFIG_CRYPTO_LRW=m
-CONFIG_CRYPTO_PCBC=m -CONFIG_CRYPTO_HMAC=y -CONFIG_CRYPTO_XCBC=m
-CONFIG_CRYPTO_MD4=m -CONFIG_CRYPTO_SHA512=m -CONFIG_CRYPTO_WP512=m
-CONFIG_CRYPTO_ANUBIS=m CONFIG_CRYPTO_BLOWFISH=m CONFIG_CRYPTO_CAMELLIA=m
Should I import all these changes in a commit? Or only POWER_RESET part.
