* Use 'consoles' instead of 'tty' to refer to interfacesSamuel Mendoza-Jonas2016-09-081-11/+14
| | | | | | | 'Console' is more readily understandable and technically more correct than 'tty' for referring to the interfaces that Petitboot starts a UI on. Signed-off-by: Samuel Mendoza-Jonas <sam@mendozajonas.com>
* hooks/add-offb: Add leading slash to HVC node pathsJeremy Kerr2016-08-081-1/+1
| | | | | | | | | | We need an absolute path to the serial@N device. It looks like some kernels aren't reading the current path correctly, leading to no console output.

* utils/hooks: Set linux,stdout-path for primary consolev1.2.0Samuel Mendoza-Jonas2016-06-291-0/+120
| | | | | | | | If the boot_tty environment variable is set, determine which device path to set in the linux,stdout-path property, which will instruct the next kernel to use it as the primary console. Signed-off-by: Samuel Mendoza-Jonas <sam@mendozajonas.com>
* utils/hooks: Write offb device address to device treeSam Mendoza-Jonas2016-02-251-0/+492
On OpenPOWER machines, kernels missing the AST video driver can use the existing 'Open Firmware' framebuffer device code to inherit an existing framebuffer from Petitboot. This requires us to translate the 64-bit address of the framebuffer 'back' into a PCI address and write it into an assigned-addresses property in the device tree.
