This changeset improves support of Timll DevKit3250 board: * added LPC32xx MAC and SMSC RMII phy support, this dependends on - http://patchwork.ozlabs.org/patch/489100/ - http://patchwork.ozlabs.org/patch/489190/ - http://patchwork.ozlabs.org/patch/491419/ - http://patchwork.ozlabs.org/patch/491420/ * added GPIO, SPI, I2C support, works good, many thanks to Albert, * added LPC32xx SLC NAND driver, testing of 50 MiB data raw reading shows 1 MiB/s speed, the same change has been sent to the mailing list separately, here it is duplicated as a build dependency: - http://patchwork.ozlabs.org/patch/495247/ - http://patchwork.ozlabs.org/patch/495250/ * added an option to pass DTB to an operating system, * changed serial console to commonly used as default UART5, * boot delay is set to 1 for convenience, * extended predefined environment variables and reserved space on NAND, * added an option to build SPL image for the board, by default SPL downloads U-boot image from NAND (offset 0x40000, size 0x60000).
Changes from v1 to v2: * addressed Albert's and Scott's comments to LPC32xx SLC NAND driver, see patch v2 2/4, * added Tegra and TI maintainers to Cc list to review/ack a change 1/4 in simple NAND SPL framework, which potentially (very unlikely) may cause a regression in NAND SPL on Tegra, TI OMAP or TI DaVinci platforms. Previous version of the change and discussion can be found here: http://lists.denx.de/pipermail/u-boot/2015-July/219253.html Albert, from commit logs I noticed that WORK92105 has SLC NAND chip, but it is managed by MLC controller, if you have any plans to test LPC32xx SLC NAND driver from the series, please *be aware* of different OOB layouts, I found it is quite easy to screw up the chip, if SLC and MLC are interchanged, so that only "nand scrub" helps. FWIW this SLC NAND driver uses a default OOB layout, the same one is found in Linux LPC32xx SLC NAND driver.
