[U-Boot] [PATCH 0/6] GE: Move from ext4 to eeprom bootcounter

[Sebastian Reichel]

Writing to ext4 from U-Boot is dangerous in case of inconsistent filesystem
state (i.e. due to power-loss). The current U-Boot code can modify the filesystem,
so that it is no longer usable by Linux after fsck. This patchset avoids writing
to the partition on GE devices by moving the boot counter to the last two bytes
of VPD EEPROM (together with some VPD cleanups). It also adds non RTC device support
to the i2c bootcounter driver.
