Import support for the Atmel AT91RM9200 CPU/Microcontroller. This SoC is a ARM920T based CPU with a bunch of built-in peripherals. The inital import supports the SPI bus, the TWI bus (although iicbus integration is not complete), the uarts, the system timer and the onboard ethernet. Support for the Kwikbyte KB9202 (http://www.kwikbyte.com) board is also included, although there's no reason why the 9200 and the 9201 wouldn't also work. Primitive support for running under the skyeye emulator is also provided (although skyeye's support for the AT91RM9200 is a little weak). The code has been structured so that other members of Atmel's arm family can be supported in the future. The AT91SAM9260 is not presently supported due to lack of hardware. The arm7tdmi families are also not supported becasue they lack an MMU. Many thanks to cognet@ for his help and assistance in bringing up this board. He did much of the vm work and wrote parts of the uart and system timer code as well as the bus space implementation. The system boots to single user w/o problem, although the serial console is a little slow and the ethernet driver is still in flux. This work was sponsored by Timing Solutions, Corporation. I am grateful to their support of the FreeBSD project in this manner.

Probe the memory size of the board better. Look at the bus width, number of banks, rows and columns the SDRAMC is programmed to access to determine the RAM size for the board, rather than hard-wiring it to be 32MB. My company's board with 64MB now probes correctly, as does the KB9202 with only 32MB. This means that to detect the right memory size, our boot loader must correctly initialize these values. This is a fairly safe assumption because the boot loader has to initialize SDRAM already, and it isn't really possible to change this register after we've accessed SDRAM.

Import support for the Atmel AT91RM9200 CPU/Microcontroller. This SoC is a ARM920T based CPU with a bunch of built-in peripherals. The inital import supports the SPI bus, the TWI bus (although iicbus integration is not complete), the uarts, the system timer and the onboard ethernet. Support for the Kwikbyte KB9202 (http://www.kwikbyte.com) board is also included, although there's no reason why the 9200 and the 9201 wouldn't also work. Primitive support for running under the skyeye emulator is also provided (although skyeye's support for the AT91RM9200 is a little weak). The code has been structured so that other members of Atmel's arm family can be supported in the future. The AT91SAM9260 is not presently supported due to lack of hardware. The arm7tdmi families are also not supported becasue they lack an MMU. Many thanks to cognet@ for his help and assistance in bringing up this board. He did much of the vm work and wrote parts of the uart and system timer code as well as the bus space implementation. The system boots to single user w/o problem, although the serial console is a little slow and the ethernet driver is still in flux. This work was sponsored by Timing Solutions, Corporation. I am grateful to their support of the FreeBSD project in this manner.
