Hans de Goede accc9e446b sunxi: Add CONFIG_OLD_SUNXI_KERNEL_COMPAT Kconfig option
Add a Kconfig option which users can select when they want to boot older
kernels, e.g. the linux-sunxi 3.4 kernels. For now this just forces the pll5
"p" value to 1 (divide by 2) as that is what those kernels are hardcoded too,
in the future this may enable further workarounds.

boolean "Enable workarounds for booting old kernels"

---help---
Set this to enable various workarounds for old kernels, this results in
sub-optimal settings for newer kernels, only enable if needed.
config MMC0_CD_PIN
string "Card detect pin for mmc0"
default ""
---help---
Set the card detect pin for mmc0, leave empty to not use cd. This
takes a string in the format understood by sunxi_name_to_gpio, e.g.
PH1 for pin 1 of port H.
config MMC1_CD_PIN
string "Card detect pin for mmc1"
default ""
---help---
See MMC0_CD_PIN help text.
config MMC2_CD_PIN
string "Card detect pin for mmc2"
default ""
---help---
See MMC0_CD_PIN help text.
config MMC3_CD_PIN
string "Card detect pin for mmc3"
default ""
---help---
See MMC0_CD_PIN help text.
config MMC_SUNXI_SLOT_EXTRA
int "mmc extra slot number"
default -1
---help---
sunxi builds always enable mmc0, some boards also have a second sdcard
slot or emmc on mmc1 - mmc3. Setting this to 1, 2 or 3 will enable
support for this.
