* CAM5200 is a TQM5200B based board. Additionally it also features
* a NIOS cpu. The NIOS CPU peripherals are accessible through MPC5xxx
* Local Bus on CS5. This includes 32 bit wide RAM and SRAM as well as
* 16 bit wide flash device. Big Endian order on a 32 bit CS5 makes
* access to flash chip slightly more complicated as additional byte
* swapping is necessary within each 16 bit wide flash 'word'.
*
* This driver's task is to handle both flash devices: 32 bit TQM5200B
* flash chip and 16 bit NIOS cpu flash chip. In the below
* flash_addr_table table we use least significant address bit to mark
* 16 bit flash bank and two sets of routines *_32 and *_16 to handle
* specifics of both flashes.

U-Boot for the TQ Systems TQMa6 modules
This file contains information for the port of
U-Boot to the TQ Systems TQMa6 modules.
1. Boot source
--------------
The following boot source is supported:
- SD/eMMC
- SPI NOR
2. Building
------------
To build U-Boot for the TQ Systems TQMa6 modules:
make tqma6<x>_<baseboard>_<boot>_config
make
x is a placeholder for the CPU variant
q - means i.MX6Q/D: TQMa6Q (i.MX6Q) and TQMa6D (i.MX6D)
s - means i.MX6S: TQMa6S (i.MX6S)
baseboard is a placeholder for the boot device
mmc - means eMMC
spi - mean SPI NOR
This gives the following configurations:
tqma6q_mba6_mmc_config
tqma6q_mba6_spi_config
tqma6s_mba6_mmc_config
tqma6s_mba6_spi_config
