This patch adds the changes to boards.cfg and the board directory under board/tqc. TQMa6 is a family of modules based on Freescale i.MX6. It consists of TQMa6Q (i.MX6 Quad), TQMa6D (i.MX6 Dual) featuring eMMC, and 1 GiB DDR3 TQMa6S (i.MX6 Solo) featuring eMMC and 512 MiB DDR3 The modules need a baseboard. Initially the MBa6x starterkit mainboard is supported. To easy support for other mainboards the functionality is splitted in one file for the module (tqma6.c) and one file for the baseboard (tqma6_ mba6). The modules can be boot from eMMC (on USDHC3) and SPI flash. The following features are supported: - MMC: eMMC on module (on USDHC3) and SD-card (on MBa6x mainboard) - Ethernet: RGMII using micrel KSZ9031 phy on MBa6x mainboard for TQMa6<x> module. The phy needs special configurations for the pad skew registers to adjust for the signal routing. Also support for standard ethernet commands and uppdate via tftp. - SPI: ECSPI1 with bootable serial flash on module and two additional chip selects on MBa6x - I2C: This patch adds support for the I2C busses on the TQMa6<x> modules (I2C3) and MBa6x baseboards (I2C1). The LM75 temperature sensors on TQMa6<x> and MBa6x are also configured. - USB: high speed host 1 on MBa6x and support for USB storage - PMIC: support for pfuze 100 on TQMa6<x> Signed-off-by: Markus Niebel <Markus.Niebel@tq-group.com>

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
|
