2.6.13 patch for AT91RM9200 (01/09/2005)


AT91RM9200 support updated for 2.6.13.
- USB Host: Do not take controller out of reset in at91_start_hc() [Eric Benard]
- Moved at91_spi.h to include/asm-arm/arch-at91rm9200/
- Changes proposed by Alexey Dobriyan:
+ Space before star, when using pointers.
+ Order in structures
+ C99-style initializers (spidev, dataflash, nand, i2c)
+ Replace BYTE_SWAP4() with swab32() [David Brownell]
- PCMCIA: Fixed order of calls in at91_cf_remove() [Steven Scholz]
- GPIO: at91_set_gpio_direction() replaced with at91_set_gpio_input() and at91_set_gpio_output().
- Ethernet: Converted to ethtool_ops [Eric Benard]
- Fix definition of __io() and __mem_pci [Steven Scholz]
- Support for KwikByte's KB9202 board [kb9200_dev <at> kwikbyte.com]
- Support for NAND flash with 2K page-sizes (eg Samsung K9F1G08U0A) [Zhang Qian]
- at91rm9200_irq_type() can set edge/level-triggering for FIQ [Karl Olsen]
- I2C: Set adapter.class to I2C_CLASS_HWMON [Mike Crowe]
- USB Device: USB_GADGET_SELECTED should be selected in Kconfig [Tom Rathbone]
- Definition of AT91C_SMC2_DBW was incorrect [Steven Scholz]
- Serial: uart_handle_dcd_change() and uart_handle_cts_change() already increment the port->icount counters [Russell King]
- Ethernet: Support for Altima AC101L Ethernet PHY [Andrew Lewis]
- Ethernet: Don't run MDIO interface faster than IEEE maximum of 2.5 MHz. Also removed special handling of the Intel, Realtek, and Broadcom PHY's [Karl Olsen]
- DataFlash: Different partitioning for 2M, 4M and 8M devices, taking into account the sector boundaries.
- Serial: Select between ttySx and ttyATx for the device names of the internal serial ports. [Karl Olsen]

linux & usb & swab32

We're trying to upgrage from 2.4.19 to 2.6.13. Everything is work fine except frame buffer driver. We uses S1D13506 on our board. The kernel stop booting when load frame buffer driver.

It seems that 2.6.13 for AT91RM9200-DK designed to S1D13806.
Any suggestion to make it work with S1D13506?

Below is boot message from our board
