* ARM: imx: Get the silicon version from the IIM moduleDinh Nguyen2010-11-281-31/+24
| | | | | | | | | | | Instead of reading the silicon version from ROM, we should read the SREV register from the IIM. Freescale has dropped all support for MX51 REV1.0, only MX51 REV 2.0 and 3.0 are valid. Signed-off-by: Dinh Nguyen <Dinh.Nguyen@freescale.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: imx: Add mx53 support to common msl functions.Dinh Nguyen2010-11-241-1/+18
| | | | | | | Add mx53 support to cpu.c and mm.c. Signed-off-by: Dinh Nguyen <Dinh.Nguyen@freescale.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: imx: Add core definitions for MX53Dinh Nguyen2010-11-241-18/+25
| | | | | | | | | | Add iomux, clocks, and memory map for Freescale's MX53 SoC. Add cpu_is_mx53 function to common.h. Add 3 more banks of gpio's to mxc_gpio_ports. Add MX53 phys offset address.

* ARM i.MX51: return gracefully on different socsSascha Hauer2010-11-241-0/+3
| | | | | | | | | Code called from an initcall can be maybe called for machines it's not intended for. So check for valid machines and return gracefully if an incompatible machine is found. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: mxc: turn off HWCAP_NEON for older versions of imx51 siliconAmit Kucheria2010-10-011-0/+19
| | | | | | | | | | Versions of silicon older than TO3 have broken NEON implementation. Turn off NEON in such cases.

* i.MX51: determine silicon revision dynamicallySascha Hauer2010-03-191-0/+53
| | | | | | | | Freescale redboot passes the silicon revision via ATAG_REVISION. Remove this bootloader dependency by doing the same as redboot does in the Kernel. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* mxc: Core support for Freescale i.MX5 seriesAmit Kucheria2010-02-091-0/+47
