[linux-sunxi] [PATCH] [V2] ARM: dts: sun7i: Add dts file for Bananapi M1 Plus board

From: Luo Yi Add support for the Bananapi M1 Plus A20 development board from sinovoip.com.cn . This board is nearly a clone of the Lemaker's Bananapro, but differ with the wlan chipset connection and i2s pinout. And I also enable the integrated audio codec on default. ---

[linux-sunxi] [PATCH v2 5/7] spl: nand: sunxi: rework status polling loop

check_value_xxx() helpers are using a 1ms delay between each test, which can be quite long for some operations (like a page read on an SLC NAND). Since we don't have anything to do but to poll this register, reduce the delay between each test to 1us. While we're at it, rename the

[linux-sunxi] [PATCH v2 1/7] spl: nand: sunxi: remove support for so-called 'syndrome' mode

The sunxi SPL NAND controller driver supports use 'BootROM'-like configs, that is, configs where the ECC bytes and real data are interleaved in the page instead of putting ECC bytes in the OOB area. Doing that has several drawbacks: - since you're interleaving data and ECC bytes you can't use the

[linux-sunxi] [PATCH v2 4/7] spl: nand: sunxi: stop guessing the redundant u-boot offset

Use CONFIG_SPL_NAND_U_BOOT_OFFS_REDUND value instead of trying to guess where the redundant u-boot image is based on simple (and most of the time erroneous) heuristics. Signed-off-by: Boris Brezillon Acked-by: Hans de Goede ---

[linux-sunxi] [PATCH v2 7/7] spl: nand: sunxi: add support for NAND config auto-detection

NAND chips are supposed to expose their capabilities through advanced mechanisms like READID, ONFI or JEDEC parameter tables. While those methods are appropriate for the bootloader itself, it's way to complicated and takes too much space to fit in the SPL. Replace those mechanisms by a dumb

[linux-sunxi] [PATCH v2 2/7] spl: nand: rename the SYS_NAND_U_BOOT_OFFS Kconfig option

The SYS_NAND_U_BOOT_OFFS is quite generic, but the Kconfig entry is forced to explicitly depend on platforms that are not already defining it in their include/configs/.h header. Rename this Kconfig option into SPL_NAND_U_BOOT_OFFS, remove the dependency on NAND_SUNXI and make it dependent on SPL

[linux-sunxi] [PATCH v2 3/7] spl: nand: support redundant u-boot image

On modern NAND it's more than recommended to have a backup copy of the u-boot binary to recover from corruption: bitflips are quite common on MLC NANDs, and the read-disturbance will corrupt your u-boot partitition more quickly than what you would see on an SLC NAND. Add an extra Kconfig option

[linux-sunxi] [PATCH v2 6/7] spl: nand: sunxi: split 'load page' and 'read page' logic

Split the 'load page' and 'read page' logic in 2 different functions so we can later load the page and test different ECC configs without the penalty of reloading the same page in the NAND cache. We also move common setup to a dedicated function (nand_apply_config()) to avoid rewriting the same

[linux-sunxi] [PATCH v2 0/7] spl: nand: sunxi: implement auto-detection

Hello, This patch series aims at adding support for NAND auto-detection to the sunxi SPL NAND driver. As explained in patch 7, this auto-detection is nothing more than a dumb "trial and error" logic, but it allows one to use the same SPL binary for all kind of sunxi boards booting from NAND. Of
