Read access to the SPI flash are broken on da850-evm, i.e. the data read is not what is actually programmed on the flash. According to the datasheet for the M25P64 part present on the da850-evm, if the SPI frequency is higher than 20MHz then the READ command is not usable anymore and only the FAST_READ command can be used to read data. This commit specifies in the DTS that we should use FAST_READ command instead of the READ command.

commit 43849785e1079f6606a31cb7fda92d1200849728 upstream.

Read access to the SPI flash are broken on da850-evm, i.e. the data
read is not what is actually programmed on the flash.
According to the datasheet for the M25P64 part present on the da850-evm,
if the SPI frequency is higher than 20MHz then the READ command is not
usable anymore and only the FAST_READ command can be used to read data.

This commit specifies in the DTS that we should use FAST_READ command
instead of the READ command.

The pinctrl pull up/down register on exynos4210 is 2-bit wide for each pin and it accepts only values of 0, 1 and 3. The pins sd4-bus-width8 were configured with value of 4. The driver does not validate the value so this overflow effectively set a bit 1 in adjacent pins thus configuring them to pull down. The author's intention was probably to set drive strength of 4x. All other bus-widths pins are configured with pull up and drive strength of 4x. Fix this one with same pattern.
