ICP DAS calls LP-8x4x 'programmable automation controller'. It is an industrial computer based on PXA270 SoC. They ship it with a 2.6.19 kernel and proprietary kernel module and userspace library to access its industrial IO.
This patch allows to boot the device with a modern kernel. It adds support for: * FPGA irq chip * MMC card interface on PXA270 * USB 1.1 port on PXA270 * 2 NOR flash devices * VGA interface on PXA270 * 2 onboard ethernet Davicom DM9000 devices * 3 serial UART ports on PXA270 Support for these devices will be added in separate patches, since they are not currently supported by the kernel: * DS1302 RTC * 512kiB SRAM * 3 built-in and up to 32 pluggable 8250 serial UART ports * industrial IO parallel bus * digital and analog industrial IO modules for parallel bus * serial interface for digital and analog industrial IO modules on parallel bus Signed-off-by: Sergei Ianovich <[email protected]> CC: Arnd Bergmann <[email protected]> --- changes v1..v2 * clean up defconfig (reduces size by 10) as suggested by Arnd Bergmann * fixed constant address definition to include (void *) cast as suggested by Arnd Bergmann * moved fixed virtual addresses into the machine source file. Header file is dropped. * static platform devices are replaced by dynamically allocated as suggested by Arnd Bergmann arch/arm/configs/lp8x4x_defconfig | 235 +++++++++++++++++++
