Add a new 'pci enum' command which re-enumerates the PCI buses. This command is enabled via the CONFIG_CMD_PCI_ENUM define and can be useful in boards with FPGAs connected via PCI/PCIe, boards that support PCI hot-plugging, or during PCI debug.
Also enable the 'pci enum' command for X-ES's Freescale-based boards.

Create a common checkboard() function to support all X-ES's Freescale boards.
Also, add a get_board_derivative() function which reads hardware strapping resistors to determine what model a board is. This allows one U-Boot image to support multiple boards.

From: John Schmoller jschmoller@xes-inc.com
Add board_flash_wp_on() to check a pca9557 gpio pin to see if non-volatile memory write protection is enabled.
Previously, write protected NOR flashes would fail initialization which resulted in a bootup error such as:
... DTT: 53 C local / 64 C remote (adt7461@4c) DTT: 54 C local (ds1621@48) FLASH: Executed from FLASH1 POST memory PASSED FLASH: ## Unknown FLASH on Bank 1 - Size = 0x00000000 = 0 MB ## Unknown FLASH on Bank 2 - Size = 0x00000000 = 0 MB *** failed *** ### ERROR ### Please RESET the board ###
With this patch, NOR flash initialization is skipped:
... DTT: 53 C local / 64 C remote (adt7461@4c) DTT: 54 C local (ds1621@48) FLASH: Executed from FLASH1 POST memory PASSED FLASH: Uninitialized - Write Protect On L2: 1024 KB enabled NAND: 1024 MiB ...
Note that flash related commands such as flinfo and saveenv will error out when flash write protection is enabled.

Some U-Boot images for X-ES boards support multiple products in the same family. For example, the XPedite5370, XPedite5371, and XPedite5372 are similar enough that one U-Boot image can work on all 3 cards. To make it clear that a U-Boot image can work on boards of the same family, rename the boards with the least significant digit of 'x'.
While we're at it, change the board config file and make targets to be lowercase.
Also change the default uImage and fdt filenames to "board.uImage" and "board.dtb" to be more generic.

Applied.
Best regards,

According to the I2C specification device address 0 is the "general call address", ie a broadcast address. The I2C specification states that the format of a general call uses at least 2 bytes, which U-Boot's probing routine does not adhere to.
Not probing device address 0 will prevent possible issues with devices that accept general calls. Additionally, this change shouldn't reduce POST coverage since each I2C device should still be accessed via its own, unique address.

Hm... it seems these patches were not compile tested on the affected boards?
Commit 60aaaa0 "post/i2c: Rename I2C_ADDR_LIST to CONFIG_SYS_POST_I2C_ADDRS" breaks building of the KUP4X, MiniFAP, TB5200, TB5200_B, cm5200, lwmon, and lwmon5 configurations like that:
Configuring for lwmon5 board... i2c.c: In function 'i2c_post_test': i2c.c:88: error: assignment of read-only location make[2]: *** [/work/wd/tmp-ppc/post/drivers/i2c.o] Error 1 make[2]: *** Waiting for unfinished jobs.... i2c.c: In function 'i2c_post_test': i2c.c:88: error: assignment of read-only location make[2]: *** [/work/wd/tmp-ppc/post/drivers/i2c.o] Error 1
Best regards,

Add the ability to not report an I2C POST error for a set of given I2C addresses on bootup. This is useful for cases when a device may or may not be present, and neither case is considered an error. For example:
- Some form factors such as XMC and Compact PCI Express have an I2C EEPROM whose address changes based on geographical address. Eg installed in one slot its EEPROM address is, 0x50, in another its 0x51, etc. This allows multiple devices to have their EEPROMs present on the same I2C bus. Thus the I2C devices present for an XMC or CPCIe card depend on if and where other cards are installed in the same system.
- Some cards have optional I2C devices. Eg one hardware build configuration has different I2C devices than another and software can't determine if the optional device should be present or not.
- Some cards have optional daughtercards with I2C devices on them.
- I2C EEPROMs address range depends on their size. Its possible to support differently size EEPROMs by only probing the EEPROM's base address and ignoring the other addresses that are impacted by its size.
A new CONFIG_SYS_POST_I2C_IGNORES define has been added which specifies a list of I2C addresses for the I2C POST to ignore.
