When 2 commands are submitted in a row, and the second is very quick, the completion of the second command might never come. This happens especially if the second command is quick, such as a status read after an erase This patch is taken from Linux: 'commit 21fc0ef9652f' ("mtd: nand: pxa3xx-nand: fix random command timeouts") Signed-off-by:Chris Packham <judge.packham@gmail.com> Signed-off-by:

When the nand is first probe, and upon the first command start, the status bits should be cleared before the interrupts are unmasked. This commit is taken from Linux: 'commit 0b14392db2e' ("mtd: nand: pxa3xx_nand: fix early spurious interrupt") Signed-off-by: -
Since the pxa3xx_nand driver was added there has been a discrepancy in pxa3xx_nand_set_sdr_timing() around the setting of tWP_min and tRP_min. This brings us into line with the current Linux code. Signed-off-by:

Don't store struct mtd_info in struct pxa3xx_nand_host. Instead use the one that is already part of struct nand_chip. This brings us in line with current U-boot and Linux conventions. Signed-off-by:

The initial buffer is used for the initial commands used to detect a flash device (STATUS, READID and PARAM). ONFI param page is 256 bytes, and there are three redundant copies to be read. JEDEC param page is 512 bytes, and there are also three redundant copies to be read. Hence this buffer should be at least 512 x 3. This commits rounds the buffer size to 2048.

Add support for changing clock rate and parent clock for Armada 37xx peripheral clocks. Only clocks which can be disabled (.can_gate is true) can have parent or rate changed. This is needed so that Turris Mox can change SPI clock in device tree. Signed-off-by:

This adds a weak definition of comphy_update_map to comphy_core, which does nothing. If this function is defined elsewhere, for example in board file, the board file can change some parameters of SERDES configuration. This is needed on Turris Mox, where the SERDES speed on lane 1 has to be set differently when SFP module is connected and when Topaz Switch module is connected. This is a temporary solution. When the comphy driver for armada-3720 will be added to the kernel, the comphy driver in u-boot shall also be updated and this should be done differently then. Signed-off-by:

The bootROM in the Armada-38x (and similar) SoC has two modes for UART boot. The first is when the normal boot media is blank (or otherwise missing the kwb header). The second is when the boot sequence has been interrupted with the magic byte sequence on the UART lines. In the first mode the bootROM routine and error code register will indicate that there was an error booting from the configured media in bits 7:0. In the second mode there is no error to indicate but the boot source is provided via bits 31:28. Handle both situations so that kwboot can be used for both boot strapping a blank board and for intercepting a regular boot sequence. Signed-off-by:

This patch accomplishes 2 things to make the kwboot procedure on the a38x more reliable. 1) We fill the tty with 1K of the magic bootparam. This helps with the timing of where the microcode picks up in the read of the line to ensure we actually catch the break to go into recovery mode 2) Before starting the xmodem transfer we sleep for 2 seconds and then flush the line. This allows all the magic bootparam to be flushed from the line and makes the xmodem transfer reliable and removes the Bad message failures. Signed-off-by:

Now that we have the pinctrl driver for Merrifield in place we can make use of it and set I2C#6 pins appropriately. Initial configuration came from the firmware. Which quite likely has been used in the phones, where that is not part of Atom peripheral, is in use. Thus we need to override the leftover. Signed-off-by:

This API is going to be used to configure some pins that are protected for simple modification. It's not a comprehensive pinctrl driver but can be turned into one when we need this in the future. Now it is planned to be used only in one place. So that's why I decided not to pollute the codebase with a full-blown pinctrl-merrifield nobody will use. This driver reads corresponding fields in DT and configures pins accordingly. The "protected" flag is used to distinguish configuration of SCU-owned pins from the ordinary ones. The code has been adapted from Linux work done by Andy Shevchenko in pinctrl-merrfifield.c Signed-off-by:
