powerpc/boot: Parse chosen/cmdline-timeout parameter

2014-11-09T22:59:30Z

On some platforms a 5 second timeout during boot might be quite long, so make it configurable. Run the loop at least once to let the user stop the boot by holding a key pressed. If the timeout is set to 0, don't wait for input, which can be used as a workaround if the boot hangs on random data coming in on the serial port.

powerpc: Bump BOOT_COMMAND_LINE_SIZE to 2048

2014-04-28T06:32:02Z

Bump the boot wrapper BOOT_COMMAND_LINE_SIZE to match the kernel. Signed-off-by: Anton Blanchard Signed-off-by: Benjamin Herrenschmidt

powerpc: Rename duplicate COMMAND_LINE_SIZE define

2014-04-28T06:31:54Z

We have two definitions of COMMAND_LINE_SIZE, one for the kernel and one for the boot wrapper. I assume this is so the boot wrapper can be self sufficient and not rely on kernel headers. Having two defines with the same name is confusing, I just updated the wrong one when trying to bump it. Make the boot wrapper define unique by calling it BOOT_COMMAND_LINE_SIZE.

powerpc: Add del_node() for early boot code to prune inapplicable devices.

2008-10-22T04:01:21Z

Some platforms have variants that can share most of a flat device tree but need a few devices selectively pruned at boot time. This adds del_node() to ops.h to allow access to the existing fdt_del_node(). Signed-off-by: Mike Ditto Signed-off-by: Benjamin Herrenschmidt

[POWERPC] Add bootwrapper function to get virtual reg from the device tree.

2008-04-17T06:01:37Z

This patch adds a new generic device tree processing function that retrieves virtual reg addresses from the device tree to the bootwrapper code. It also updates the bootwrapper code to use the new function. dt_get_virtual_reg() retrieves the virtual reg addresses from the "virtual-reg" property. If the property can't be found, it uses the "reg" property and walks the tree to translate it to absolute addresses. Signed-off-by: Laurent Pinchart Acked-by: Scott Wood Signed-off-by: Kumar Gala

[POWERPC] bootwrapper: Add find_node_by_compatible

2008-01-27T20:07:37Z

Add the ability to find a device node by just what its compatible with. This is useful in cases that we don't have a prop to find the node with. Signed-off-by: Kumar Gala

[POWERPC] bootwrapper: Add find_node_by_alias and dt_fixup_mac_address_by_alias

2008-01-24T01:32:44Z

Add the ability to set the mac address given the alias for the device. Removes the need for having a linux,network-index property. Signed-off-by: Kumar Gala

[POWERPC] Kill flatdevtree.c

2007-12-11T02:46:15Z

Now that earlier patches have switched the bootwrapper to using libfdt for device tree manipulation, this patch removes the now unused flatdevtree.c and related files. Signed-off-by: David Gibson Signed-off-by: Paul Mackerras

[POWERPC] Use embedded libfdt in the bootwrapper

2007-12-11T02:46:14Z

This incorporates libfdt (from the source embedded in an earlier commit) into the wrapper.a library used by the bootwrapper. This includes adding a libfdt_env.h file, which the libfdt sources need in order to integrate into the bootwrapper environment, and a libfdt-wrapper.c which provides glue to connect the bootwrapper's abstract device tree callbacks to the libfdt functions. In addition, this changes the various wrapper and platform files to use libfdt functions instead of the older flatdevtree.c library. Signed-off-by: David Gibson Signed-off-by: Paul Mackerras

[POWERPC] Virtex: Add uartlite bootwrapper driver

2007-10-03T12:23:13Z

Allows the bootwrapper to use the uartlite device for console output. Signed-off-by: Grant Likely Signed-off-by: Josh Boyer
