| | * | serial: ns16550: Support debug UARTSimon Glass2015-02-19-2/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add debug UART functions to permit ns16550 to provide an early debug UART. Try to avoid using the stack so that this can be called from assembler before a stack is set up (at least on ARM and PowerPC). Signed-off-by: Simon Glass <sjg@chromium.org>
| | * | serial: ns16550: Add access functions that don't need platdataSimon Glass2015-02-19-18/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For the debug UART we need to be able to provide any parameters before driver model is set up. Add parameters to the low-level access functions to make this possible. Signed-off-by: Simon Glass <sjg@chromium.org>
| | * | serial: Support an early UART for debuggingSimon Glass2015-02-19-2/+185
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| * | cmd_i2c: Provide option for bulk 'i2c write' in one transactionLubomir Popov2015-02-19-9/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I2C chips do exist that require a write of some multi-byte data to occur in a single bus transaction (aka atomic transfer), otherwise either the write does not come into effect at all, or normal operation of internal circuitry cannot be guaranteed. The current implementation of the 'i2c write' command (transfer of multiple bytes from a memory buffer) in fact performs a separate transaction for each byte to be written and thus cannot support such types of I2C slave devices. This patch provides an alternative by allowing 'i2c write' to execute the write transfer of the given number of bytes in a single bus transaction if the '-s' option is specified as a final command argument. Else the current re-addressing method is used. Signed-off-by: Lubomir Popov <l-popov@ti.com> hs: adapt to CONFIG_DM_I2C

| | * | sunxi: Support the FEL boot mode in the regular u-boot buildSiarhei Siamashka2015-02-16-10/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | So that the CONFIG_SPL_FEL option is not needed anymore. And the regular SPL binary, generated by the default u-boot build, is now also bootable over USB in the FEL mode. The SPL still can boot from the SD card too. A bunch of system registers need to be saved/restored in order to ensure that the IRQ handler still works in the BROM FEL code after getting control back from the SPL. This is done in the sunxi code instead of abusing ifdefs in 'start.S'. The decision whether to load the main u-boot binary from the SD card or return to the FEL code in the BROM is done at runtime.

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.
