Xilinx ML300 board support in linuxppc-2.4 tree

Hi,

The patch fixes/updates ML300 support in linuxppc-2.4 tree. This is mostly a move from linuxppc_2_4_devel tree with few additions:

- /proc/interrupts now contains correct information about whether the interrupt is edge triggered or level sensitive (linuxppc_2_4_devel tree shows all the interrupts as edge triggered).
For this arch/ppc/platforms/xilinx_ml300.c sets the proper bit in irq_desc[], and arch/ppc/kernel/xilinx_pic.c uses this information to decide when to acknowledge the interrupt.

- GPIO driver is fixed to support the GPIO IP as it is in EDK (GPIO IP changed from V2PDK to EDK).

- xilinx_ml300_defconfig matches the EDK reference design
(http://www.xilinx.com/ise/embedded/edk_examples.htm, example #6). The following devices are supported by default:
GPIO, IIC/RTC, UARTs (two 16x50 compatible ones), SPI, TFT LCD, PS/2 (kbd and mouse), System ACE, touchscreen, 10/100 ethernet.
UART Lite driver is included in the patch. But the reference design doesn't have UART Lites, so none is in the default configuration.

The patch is against the kernel version 2.4.25-rc2.

Hi,

This code comes from the BSP generated by EDK for Linux. Most changes are cosmetic except that Xilinx replaced the packet fifo v.1.00b driver with the v.2.00a one (used by ethernet driver only).

The patch affects Xilinx ML300 board only.

The patch itself can be found here:
http://source.mvista.com/~ank/xilinx_code_update.040319.diff

The patch is against the kernel version 2.4.26-rc4.

Best regards,

Hi,

Here is the 10/100Mb ethernet driver update for Xilinx EMAC.

New functionality added:
1) SG DMA transfer support;
2) putting more than one packet per interrupt into FIFO (FIFO mode);
3) interrupt coalesce parameters setting using ioctl commands (SGDMA mode);
4) ethtool utility support;
5) bottom half interrupts service.

Fixed:
1) memory deallocation in cleanup function;
2) setting Tx timeout in FIFO mode.

The patch affects Xilinx ML300 board only.
