* clk: i.MX6qp: Fix location of the enfc_sel muxSascha Hauer2019-09-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | On the i.MX6qp the enfc_sel mux is at bits 15-17, not on 16-17. Fix this. During clock tree initialization we reparented the enfc_sel to: clk_set_parent(clks[IMX6QDL_CLK_ENFC_SEL], clks[IMX6QDL_CLK_PLL2_PFD2_396M]); This resulted in a register setting 0b110 for the enfc_sel mux which is reserved. Apparently this reserved setting resulted in the enfc clock being driven from pll3_pfd3_454m. This means our enfc clock was the factor 454/396 too high. With b534f79112f0 ("clk: imx6: Fix procedure to switch the parent of LDB_DI_CLK") we happened to disable pll3_pfd3_454m during init, so with this commit NAND stopped working entirely on i.MX6qp. Both issues are fixed with this patch Fixes: b534f79112f0 ("clk: imx6: Fix procedure to switch the parent of LDB_DI_CLK") Fixes: 92fd61d12723 ("clk: i.MX6: Fix enfc_sel for i.MX6dqp") Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * fs: tftp: don't maintain tftp dentries in dcacheAhmad Fatoum2019-08-231-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | Currently a negative dentry is cached whenever a non-existing file was looked up over TFTP. Short of a barebox reset, there is no way to invalidate that dentry, so barebox retries the look up. Fix this by always reporting TFTP dentries as invalid in the d_revalidate callback.

It takes a single partition for both the xload images and the barebox images. It uses a fixed layout on this partition, so there's no need to configure anything on the board side.

Bad blocks are automatically skipped and before anything is done we check if the image will fit into the remaining space (honouring bad blocks). Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

Without it of_mdio_find_phy() will not find the right device. It will match: bus->parent->device_node == phy_node->parent Without this patch bus->parent->device_node will be the ethernet node and phy_node->parent will be the ti,cpsw-mdio node. With the MDIO device node registered as device of its own both nodes above will be the ti,cpsw-mdio node. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * | | | | | mtd: nand: gpmc: Add BCH16 supportSascha Hauer2019-08-284-9/+330

The support is mostly taken from Linux-5.3-rc6. One major change is the different wrap mode used. The Kernel uses wrapmode 1, which means "pass all data through the BCH engine". Still the Kernel has to skip the OOB marker which is done by reading all user data, then use NAND_CMD_RNDOUT to position right behind the OOB marker and then read the ECC data. Instead of doing this we use wrap mode 4 which allows us to bypass the OOB marker from the BCH engine automatically. This explains bch_wrapmode = 1, eccsize0 = 0, eccsize1 = 52 vs. bch_wrapmode = 4, eccsize0 = 4, eccsize1 = 52 Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
