[U-Boot] [PATCH v2] net: phy: marvell: Add functions to read PHY's extended registers
by Lukasz Majewski 22 Jan '18

22 Jan '18

This commit allows extended Marvell registers to be read with: foo > mdio rx FEC 3.10 Reading from bus FEC PHY at address 0: 3.16 - 0x1063 foo > mdio wx FEC 3.10 0x1011 The above code changes the way ETH connector LEDs blink.

[U-Boot] [PATCH] net: macb: Add support for Xilinx Zynq SoC
by Wilson Lee 22 Jan '18

22 Jan '18

Although Xilinx Zynq SoC was using MACB similar hardware. However, U-boot MACB driver was not supporting Xilinx Zynq SoC. This patch is to add support for the Xilinx Zynq SoC to the existing MACB network driver. This patch is to add Zynq GEM DMA Config, provide callback function for different linkspeed for case of using Xilinx Zynq Programmable Logic as GMII to RGMII convertor. This patch convert the return value to use error codes.

[U-Boot] [PATCH v2] spi: kirkwood_spi: implement workaround for FE-9144572
by Chris Packham 22 Jan '18

22 Jan '18

Erratum NO. FE-9144572: The device SPI interface supports frequencies of up to 50 MHz. However, due to this erratum, when the device core clock is 250 MHz and the SPI interfaces is configured for 50MHz SPI clock and CPOL=CPHA=1 there might occur data corruption on reads from the SPI device. Implement the workaround by setting the TMISO_SAMPLE value to 0x2 in the timing1 register.

[U-Boot] [PATCH v4 0/6] Support for the Turris Omnia router
by Marek Behún 22 Jan '18

22 Jan '18

This is the fourth version of patches for adding support for the Turris Omnia board, a router developed by the CZ.NIC. Modifications from last version: - Since the new driver model API does not expose the watchdog_reset function, only wdt_reset, the watchdog did not get restarted and the device rebooted every 2 minutes in U-Boot. These patches solve this problem. - The SPI flash could not be accessed. I did not notice this since during my testing I always uploaded the SPL image via serial line. This is now also solved. The first patch modifies Marvell's DDR3 training code to be more general, so that board topology map can force 2t timing. The second patch adds support for the hardware watchdog which can be found on Omnia. I have modified the driver to use the new driver model API. The third patch adds the device tree for Turris Omnia taken from Linux kernel and also armada-385-turris-omnia-u-boot.dtsi file with some additions for U-Boot. The fourth patch adds support for the I2C multiplexer found on Turris Omnia. The fifth patch adds support for the ATSHA204A CryptoAuthentication chip, on which the Turris Omnia stores serial number and device MAC address. The sixth patch adds the proper support for the board. I have modified config to use distro defaults as requested by Andreas Faerber and also removed unnecessary comments. Marek Behun

[U-Boot] [PATCH] patman: Unquote output from get_maintainer.pl
by Stefan Brüns 22 Jan '18

22 Jan '18

get_maintainer.pl quotes names which it considers unsafe, i.e. anything containing [^a-zA-Z0-9_ \-]. This confuses patman, it will duplicate addresses which are also in Series-to/cc. Strip the quotes.

[U-Boot] [PATCH v4] drivers: core: Add translation in live tree case
by Mario Six 22 Jan '18

22 Jan '18

The function dev_read_addr calls ofnode_get_addr_index in the live tree case, which does not apply bus translations to the address read from the device tree. This results in illegal addresses on boards that rely on bus translations being applied. Fix this situation by applying bus translations in the live tree case as well.
