* sunxi: Configure only LVDS pins instead of all LCD pins when LVDS interface ↵Lawrence Yu2016-03-23-0/+4
| | | | | | | | | | | | | | | | | | | selected The behavior before this patch would attempt to configure the mux setting for pins 0 to 27 on PORTD to all be setting 3 for LVDS. The LVDS interface actually only uses pins 18 to 27 and not pins 0 to 27 as in the parallel LCD interface. This patch restricts the configuration to only the relevant pins 18 to 27 on PORTD. This was tested on a sun8i A33 tablet with an LVDS screen. MMC1 has the capability to use pins 2 to 7 on PORTD and the mux on those pins was being inadvertently set to setting 3 for MMC functionality which this patch corrects.

* x86: broadwell: Add video supportSimon Glass2016-03-17-1/+1174
| | | | | | | | | | | | | | Add a video driver for Intel's broadwell integrated graphics controller. This uses a binary blob for most init, with the driver just performing a few basic tasks. This driver supports VESA as the mode-setting mechanism. Since most boards don't support driver model yet with VESA, a special case is added to the Kconfig for broadwell. Eventually all boards will use driver model and this can be removed. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Bin Meng <bmeng.cn@gmail.com>

| * video: bcm2835: use bus_to_phys() on FB addressStephen Warren2016-02-06-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The FB address is generated by the firmware running on the GPU/VideoCore and is a "bus" address. This address is the other side of an IOMMU from the ARM upon which U-Boot is running. Use bus_to_phys() to convert this to an ARM physical address. Without this, U-Boot seems to work just fine, but once the Linux kernel boots on an RPi2, accessing the FB memory often causes a hard system hang.

* video: Add a console driver that uses TrueType fontsSimon Glass2016-01-30-2/+580
| | | | | | | | | | | | | | | | | | | The existing 8x16 font is adequate for most purposes. It is small and fast. However for boot screens where information must be presented to the user, the console font is not ideal. Common requirements are larger and better-looking fonts. This console driver can use TrueType fonts built into U-Boot, and render them at any size. This can be used in scripts to place text as needed on the display. This driver is not really designed to operate with the command line. Much of U-Boot expects a fixed-width font. But to keep things working correctly, rudimentary support for the console is provided. The main missing feature is support for command-line editing. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Anatolij Gustschin <agust@denx.de>
