Changes since U-Boot 1.1.4:
|
||||
======================================================================
|
||||
|
||||
* Update for CAM5200 board:
|
||||
- Map in a additional chip selects CS4 and CS5.
|
||||
- Modify the port configration, configure six UARTs and no PCI,
|
||||
ATA and USB.
|
||||
- Add custom flash driver to handle specific byte swapping
|
||||
|
||||
* Fix TLB setup for Ocotea board

* 101 -> PSC6 : Extended POST test is not available
|
||||
* on MINI-FAP and TQM5200_IB:
|
||||
* use PSC6_0 to PSC6_3 as GPIO: Bits 9:11 (mask: 0x00700000):
|
||||
* 000 -> PSC6 could not be used as UART, CODEC or IrDA
|
||||
* GPIO on PSC6_3 is used in post_hotkeys_pressed() to enable extended POST
|
||||
* tests.
|
||||
* 00 -> No Alternatives, CAN1/2 on PSC2 according to PSC2 setting.
|

* use ATA: Bits 6-7 (mask 0x03000000):
|

* Use for CAM5200 board.
|

* Extended POST test is not available.
|

* Use for STK52xx, FO300 and CAM5200 boards.
|
||||
* use PCI_DIS: Bit 16 (mask 0x00008000):
|
||||
* 1 -> disable PCI controller (on CAM5200 board).
|

* use USB: Bits 18-19 (mask 0x00003000):
|
||||
* 10 -> two UARTs (on FO300 and CAM5200).
