| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All the info we need to pass to transport function can be captured in a struct us_blk_dev and two byte arrays, so having a dedicated struct with many unused fields doesn't really buy us anything. Drop the struct and convert the rest of the code to pass needed data explicitly. Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

This is based on U-Boot-2019.01 but with many adjustments: - PowerPC support has been removed - CPP #ifdeffery replaced with C - No more global variables/functions expected from the driver, configuration is passed by the board code which calls the driver We already have the driver in the tree in an older version forked from U-Boot-2013.04. This version lacks Layerscape support and many quirks in the driver are PowerPC specific. Since the existing driver should work on all known PowerPC and PowerPC is a dead end I decided not to improve the existing driver and instead add a new Layerscape specific driver.

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | For the new "fixed-partitions" binding we ignore the partitions subnode for creating reproducible names and set node to its parent. To get the number of address cells we must call of_n_addr_cells() before setting node to its parent though, not afterwards. With the current behaviour we always get OF_ROOT_NODE_ADDR_CELLS_DEFAULT (=1). This happens to work then the partitioned device is less than 4GiB in size. On bigger devices #address-cells = <2> is chosen by the mtd partition fixup code. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Reported-by: Bastian Krause <bst@pengutronix.de>
