[U-Boot] [PATCH v6 0/3] Support for XPedite5370 and misc GPIO

[Peter Tyser <ptyser@xes-inc.com>]

NOTE: If there are still concerns about the ds4510 driver, feel
free to leave it out of this patch series and only apply
"Add support for PCA953x I2C gpio devices" and "XPedite5370
board support".  I'd rather get those 2 changes merged in for
the upcoming release and deal with the ds4510 later if need be.


Hello,
This patch series adds support for the XPedite5370 SBC.
Its an MPC8572-based VPX card with a PMC/XMC site.  The
XPedite5370 includes a significant number of I2C GPIO devices (5)
which are used for board configuration.  I added support for
2 new I2C gpio devices in a new drivers/gpio directory.  I'm
not sure if this is the preferred location/method, so let me know
if others have have different preferences.  It'd be nice to have a
more generic GPIO framework (like Linux's) at some point, but
figured this was a step in the right direction by providing a
place for generic GPIO devices in drivers/gpio.

Thanks,
Peter

Changes since v1:
- Rebased to u-boot-mpc85xx tree
- Updated NOR flash remapping method
- Added CONFIG_SYS_I2C2_OFFSET define to XPEDITE5370.h
- Removed CONFIG_SYS_EEPROM_PAGE_WRITE_ENABLE from XPEDITE5370.h

Changes since v2:
pca953x.c:
- Use cmd_tbl_t for subcommand parsing
- Made 'info' command dependent on CONFIG_CMD_PCA953X_INFO
- Removed chip command parameters, added 'device' subcommand

ds4510.c:
- Use cmd_tbl_t for subcommand parsing
