| | * sunxi: musb: Check Vbus-det before enabling otg port powerHans de Goede2015-02-211-0/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sending out 5V when there is a charger connected to the otg port is not a good idea, so check for this and error out. Note this commit currently breaks otg support on the q8h tablets, as we need to do some magic with the pmic there to get vbus info, this is deliberate (better safe then sorry), fixing this is on my TODO list.

| | | | | | | | | | | | | | | | | | | | | | | | | | | High Capacity (e)MMC cards work fine on sun4i / sun5i, and not having this capability set causes u-boot to not recognize the eMMC on an Utoo P66 A13 tablet, so always set it thereby fixing this.

| * | serial: Support an early UART for debuggingSimon Glass2015-02-191-0/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This came up in a discussion on the mailing list here: https://patchwork.ozlabs.org/patch/384613/ My concerns at the time were: - it doesn't need to be written in assembler - it doesn't need to be ARM-specific This patch provides a possible alternative. It works by allowing any serial driver to export one init function and provide a putc() function. These can be used to output debug data before the real serial driver is available. This implementation does not depend on driver model, and it is possible for it to operate without a stack on some architectures (e.g. PowerPC, ARM). It provides the same features as the ARM-specific debug.S but with more UART and architecture support. Signed-off-by: Simon Glass <sjg@chromium.org>

This makes u-boot properly see the framebuffer as dram, and initalize the level 2 cache for it, fixing the very slow cfb scrolling problem. As an added bonus this stops us from reserving the framebuffer when simplefb is not used because an older kernel is booted, or hdp is used and no hdmi cable was plugged in, freeing up the memory for kernel use in these cases.
