2018-12-06mtd: sf: Make sure we don't register the same device twiceBoris Brezillon
spi_flash_mtd_register() can be called several times and each time it will register the same mtd_info instance like if it was a new one. The MTD ID allocation gets crazy when that happens, so let's track the status of the sf_mtd_info object to avoid that.

2018-12-06mtd: Add a function to report when the MTD dev list has been updatedBoris Brezillon
We need to parse mtdparts/mtids again everytime a device has been added/removed from the MTD list, but there's currently no way to know when such an update has been done. Add an ->updated field to the idr struct that we set to true every time a device is added/removed and expose a function returning the value of this field and resetting it to false.

2018-11-22mtd: rawnand: pxa3xx: fix 2kiB pages with 8b strength chips layoutMiquel Raynal
The initial layout for such NAND chips was the following: +----------------------------------------------------------------------------+ | 1024 (data) | 30 (ECC) | 1024 (data) | 30 (ECC) | 32 (free OOB) | 30 (ECC) | +----------------------------------------------------------------------------+ This layout has a weakness: reading empty pages trigger ECC errors (this is expected), but the hardware ECC engine tries to correct the data anyway and creates itself bitflips, hence bitflips are detected in erased pages while actually there are none in the NAND chip. Two solutions have been found at the same time. One was to enlarge the free OOB area to 64 bytes, changing the layout to be: +----------------------------------------------------------------------------+ | 1024 (data) | 30 (ECC) | 1024 (data) | 30 (ECC) | 64 (free OOB) | 30 (ECC) | +----------------------------------------------------------------------------+ ^^ The very big drawbacks of this solution are: 1/ It prevents booting from NAND. 2/ The current Linux driver (marvell_nand) does not have such problem because it already re-reads possible empty pages in raw mode before checking for bitflips. Using different layouts in U-Boot and Linux would simply not work. As this driver does support raw reads now and uses it to check for empty pages, let's forget about this broken hack and return to the initial layout with only 32 free OOB bytes.

2018-11-22mtd: nand: pxa3xx: re-read a page in raw mode on uncorrectable errorMiquel Raynal
This only applies on BCH path. When an empty page is read, it triggers an uncorrectable error. While this is expected, the ECC engine might produce itself bitflips in the read data under certain layouts. To overcome this situation, always re-read the entire page in raw mode and check for the whole page to be empty. Also report the right number of bitflips if there are any.

2018-11-20arm64: mvebu: a8k: autodetect RAM sizeBaruch Siach
Some Armada 8K boards like Macchiatobin and Clearfog GT-8K use RAM from external DIMM. Hard coding the RAM size in the device-tree is not convenient. Fortunately, the ATF that initializes the RAM knows the size of RAM, and U-Boot can query the ATF using a SMC call. The ATF maps the lower 3G of RAM starting at address 0. Higher RAM is mapped at 4G. This leaves a 1G hole between 3G and 4G for IO peripherals. Use a second bi_dram[] entry to describe the higher RAM area. As a result, CONFIG_NR_DRAM_BANKS must be set to 2 to use more than 3GB RAM. This code in this commit is mostly taken from downstream Marvell U-Boot code by Grzegorz Jaszczyk.
