* arm: socfpga: fpga: Add SoCFPGA FPGA programming interfacePavel Machek2014-10-06-0/+305
| | | | | | | | | | | | | | | | | | | Add code necessary to program the FPGA part of SoCFPGA from U-Boot with an RBF blob. This patch also integrates the code into the FPGA driver framework in U-Boot so it can be used via the 'fpga' command.

Note that it also includes a fix: - writel(~KWSPI_CSN_ACT | KWSPI_SMEMRDY, &spireg->ctrl); + writel(KWSPI_SMEMRDY, &spireg->ctrl); Here the bit KWSPI_CSN_ACT (0x1) should have been cleared. Instead 0xfffffffe is written into this control register. This is the main reason to use the clrsetbits() functions now. As they make clearing bits much less error prone. Additionally KWSPI_IRQUNMASK is not used in spi_cs_activate() and spi_cs_deactivate() any more. Its the wrong macro but has the same value as the correct one (KWSPI_CSN_ACT). This is in preparation for use of this driver on the Marvell Armada XP platform as well.

This is set up by embedding the GPIO information in the CS value: cs = (cs | gpio << 8) This merge of cs and gpio data into one value breaks the sf probe command: if the use of gpio is required, invoking "sf probe <cs>" will not work, because the CS argument doesn't have the GPIO information in it. Instead, the user must use "sf probe <cs | gpio << 8>". For example, if bank 2 gpio 30 is used to force cs high on cs 0, bus 0, then instead of typing "sf probe 0" the user now must type "sf probe 15872". This is inconsistent with the description of the sf probe command, and forces the user to be aware of implementaiton details. Fix this by introducing a new board function: board_spi_cs_gpio(), which will accept a naked CS value, and provide the driver with the relevant GPIO, if one is necessary.

* mtd: atmel-nand: use pmecc_readl(b)/pmecc_writel to access the pmecc registerWu, Josh2014-09-19-10/+14
| | | | | | | | | | We defined the macro pmecc_readl(b)/pmecc_writel for pmecc register access. But in the driver we also use the readl(b)/writel. To keep consistent, this patch make all use pmecc_readl(b)/pmecc_writel.

| | | | | | | | | | | | | | | | | | | | | | | | UART does not use the UART FIFO, but we should also not rely that the UART FIFO is diabled by default. For instance, when loading U-Boot using the boot ROMs serial downloader protocol over UART, FIFO is enabled at U-Boot start time. This patch disables the RX and TX FIFO, sets back their thresholds and flushes them. Signed-off-by: Stefan Agner <stefan@agner.ch>
| * arm: vf610: lpuart: fix status register handlingStefan Agner2014-09-09-6/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The status register 1 (S1) is not writeable, hence we should not write it. In order to clear the RDRF flag we only need to read the data register. Also, when stressing U-Boot a lot with serial input, an overflow can occur which asserts the S1_OR flag (while not asserting the S1_RDRF flag). To clear this flag we again just need to read the data register, hence add this flag to the abort conditions for the while loop. Insert a compiler barrier to make sure reading the data register gets executed after reading the status register. Signed-off-by: Stefan Agner <stefan@agner.ch>
