| | | | | | | | | | | | | Add support for specifying a differnt CPU for main u-boot and SPL u-boot builds. This is done by adding an optional SPL CPU after the main CPU in boards.cfg as follows: normal_cpu:spl_cpu This this case CPU will be set to "normal_cpu" during the main u-boot build and "spl_cpu" during the SPL build.

But to make return type uniform across the file changed to u32 Similarly, parameter passed to out_8, out_be16, out_le16 ,out_be32 & out_le32 should not be 'int'.Change it to type u8/u16/u32.

* sandbox: Add basic test for command executionSimon Glass2012-08-09-0/+131
| | | | | | | | | | | | | | | | | | | Since run_command() and run_command_list() are important and a little confusing, add some basic tests to check that the behaviour is correct. Note: I am not sure that this should be committed, nor where it should go in the source tree. Comments welcome. To run the unit tests use the ut_cmd command available in sandbox: make sandbox_config make ./u-boot -c ut_cmd (To test both hush and built-in parsers, you need to manually change CONFIG_SYS_HUSH_PARSER in include/configs/sandbox.h and build/run again) Signed-off-by: Simon Glass <sjg@chromium.org>
* Allow newlines within command environment varsSimon Glass2012-08-09-3/+3
| | | | | | | | | | | | Any environment variable can hold commands to be executed by the 'run' command. The environment variables preboot, bootcmd and menucmd have special code for triggering execution in certain circumstances. We adjust these calls to use run_command_list() instead of run_command(). This change permits these variables to have embedded newlines so that they work the same as the 'source' command. Signed-off-by: Simon Glass <sjg@chromium.org>
* Add run_command_list() to run a list of commandsSimon Glass2012-08-09-65/+102
| | | | | | | | | This new function runs a list of commands separated by semicolon or newline. We move this out of cmd_source so that it can be used by other code. The PXE code also uses the new function. Suggested-by: Michael Walle <michael@walle.cc> Signed-off-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | | | | | | | | | | | The SET_PCI_LIODN() macro takes a compatible property string as a parameter, so that it knows which PCI device tree node to look for. The calls to these macros are using a hard-coded string, but we already have the CONFIG_SYS_FSL_PCIE_COMPAT macro which contains the same string, so we should use that.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PHYs on SGMII riser card are used in SGMII mode with different external IRQs from eTSEC. This means in SGMII mode phy-handle and phy-connection-type under ethernet node should be updated. Otherwise the PHY interrupt can not be handled therefor PHY link state change can not be auto detected. For we have seperate SGMII PHY nodes, ethernet PHY reg fixup is not needed but it's still be kept to guarantee the sgmii mode could work with old device tree.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Lane muxing on p2041 is controlled by a reg in CPLD, offset of this reg is 0xc, CPLD supports SATA by default, we should re-configure the lane muxing according to RCW, which indicates what SerDes protocol it is running. Default lane muxing map is as below: Lane G on bank1 routes to SGMII, controlled by bit 1 of the reg; Lane A on bank2 routes to AURORA, controlled by bit 0 of the reg; Lane C/D on bank2 routes to SATA0 and SATA1, controlled by bit 2 and bit 3 respectively. Default value of these bits for lane muxing is '1', we should set or clear these bits accoring to RCW.

| | | | | | | | | | | | | | | | | | | | | | In order for indirect mode on the PIXIS to work properly, both chip selects need to be set to GPCM mode, otherwise writes to the chip select base addresses will not actually post to the local bus -- they'll go to the NAND controller instead.

To support both boards with the same u-boot we use here the SDRAM detection. This patch enables SDRAM detection between 256MB and 128MB. So in addition to the existing 256MB geometry: 4 chips x 8M (13 rows, 10 cols) x 16 bit x 4 banks we can now also have 128MB geometry: 4 chips x 4M (13 rows, 9 cols) x 16 bit x 4 banks Signed-off-by: Gerlando Falauto <gerlando.falauto@keymile.com>
