* ARMV7: OMAP: Overo: Autodetect presence/absence of transceiver on mmc2Steve Sakoman2010-09-08-2/+80
| | | | | | | | | | An upcoming version of Overo uses a Wifi/BT module with 1.8V signaling, eliminating the need for an external transceiver to handle the level shifting. This patch detects whether an external transceiver is present and adjusts the pinmux settings as appropriate.

* ARMV7: OMAP3: Add support for Beagle xMSteve Sakoman2010-09-08-5/+44
| | | | | | | | This patch adds support for the Beagle xM. It uses the board ID GPIO bits to recognize this revision and perform appropriate setup. Signed-off-by: Steve Sakoman <steve@sakoman.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
* ARMV7: OMAP3: Add CONFIG_SYS_NAND_QUIET_TEST to Beagle and Overo configsSteve Sakoman2010-09-08-0/+2
| | | | | | | | Future versions of these boards have options for POP memory with no NAND. This option prevents display of error messages when no NAND is detected. Signed-off-by: Steve Sakoman <steve@sakoman.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>

* ARMV7: OMAP3: Remove erroneous hard coded sdram setup for 128MB/bankSteve Sakoman2010-09-08-22/+21
| | | | | | | | | Upcoming Beagle and Overo revisions use POP memory with 256MB or 512MB per bank. This patches uses the SDRC settings from x-load or the config header to set up timing properly. Signed-off-by: Steve Sakoman <steve@sakoman.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>

| | | | | | | | Using the reset command on OMAP36XX/37XX and OMAP4 caused a hang. This patch uses the reset bit appropriate for each CPU architecture. Signed-off-by: Steve Sakoman <steve@sakoman.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>

| | | | | | | | | | The workarounds for errata 621766 and 725233 should only be applied on affected Cortex-A8 revisions. Recent chips use r3px cores where these have been fixed.

* ARMV7: OMAP3: Convert setup_auxcr() to pure asmMans Rullgard2010-09-08-35/+19
| | | | | | | | | | | This function consists entirely of inline asm statements, so writing it directly in a .S file is simpler. Additionally, the inline asm is not safe as is, since registers are not guaranteed to be preserved between asm() statements.

* ARMV7: OMAP3: Fix and clean up L2 cache enable/disable functionsMans Rullgard2010-09-08-54/+21
| | | | | | | | | | | | | | | | On OMAP34xx ES1.0, the L2 enable bit can only be set in secure mode, so an SMC call to the ROM monitor is required. On later versions, and on newer devices, this bit is banked and we can set it directly. The code checked only the ES revision of the chip, and hence incorrectly used the ROM call on ES1.0 versions of other devices. This patch adds a check for chip family as well as revision, and also removes some code duplication between the enable and disable functions.

The ICS bits where incorrectly shifted. This bug was found on the lwmon5 board, which uses bootstrap option H (I2C bootstrap EEPROM). Additionally a bit of code was moved into the if statement, since its only used after later on. No need to run this code all the time. Also, a few empty lines are added to make the code better readable. Signed-off-by: Stefan Roese <sr@denx.de> Cc: Rupjyoti Sarmah <rsarmah@amcc.com> Cc: Victor Gallardo <vgallardo@appliedmicro.com>

| * | nios2: fix out of reach case for do_resetThomas Chou2010-08-19-6/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a limitation (or bug?) of nios2 toolchain. The nios2 gcc didn't generate correct code when the reset vector is passed as a constant. It just generated a direct "call", which was wrong when the reset vector was not located in the same 256MB span as u-boot. The "Nios II Processor Reference Handbook" said, "call can transfer execution anywhere within the 256 MByte range determined by PC31..28. The Nios II GNU linker does not automatically handle cases in which the address is out of this range." So we have to use registered "callr" instruction to do the job.
