fsl_esdhc_imx driver will call "mxc_get_clock(MXC_ESDHC_CLK + dev->seq)", however mxc_get_clock wrongly handle MXC_ESDHC_CLK as root clk and cause sd card could not be detected in U-Boot proper, as below: "Loading Environment from MMC... unable to select a mode" Handle MXC_ESDHC_CLK in mxc_get_clock to fix the issue.

2020-01-07ARM: mxs: spl_boot.c: make early_delay more robustRasmus Villemoes
It's true that booting normally doesn't take long enough for the register to roll (which actually happens in a little over an hour, not just a few seconds). However, the counter starts at power-on, and if the board is held in reset to be booted over USB, one actually risks hitting wrap-around during boot, which can both result in too short delays (if the "st += delay" calculation makes st small) and theoretically also unbound delays (if st ends up being UINT_MAX and one just misses sampling digctl_microseconds at that point). It doesn't take more code to DTRT, and once bitten, twice shy. Signed-off-by: Rasmus Villemoes <rasmus.villemoes@prevas.dk>

The EDIMM STARTER KIT i.Core 1.5 MIPI Evaluation is based on the 1.5 version of the i.Core MX6 cpu module. The 1.5 version differs from the original one for a few details, including the ethernet PHY interface clock provider. With this commit, the ethernet interface works properly: SMSC LAN8710/LAN8720 2188000.ethernet-1:00: attached PHY driver While before using the 1.5 version, ethernet failed to startup do to un-clocked PHY interface: fec 2188000.ethernet eth0: could not attach to PHY Similar fix has merged for i.Core MX6Q but missed to update for DL.

2020-01-07arm: mxs: be more careful when enabling gpmi_clkRasmus Villemoes
The data sheet says that the DIV field cannot change while the CLKGATE bit is set or modified. So do it a little more carefully, by first clearing the bit, waiting for that to appear, then setting the DIV field. Signed-off-by: Rasmus Villemoes <rasmus.villemoes@prevas.dk>

I tried clearing a bit by writing to hw_clkctrl_gpmi_clr, then busy-waiting for it to actually clear. My board hung. The data sheet agrees, these registers do not have _set, _clr, _tog, so fix up the definitions. git grep -E 'clkctrl_(gpmi|ssp[0-9])_' says that nobody uses those non-existing ops registers.

2020-01-07ddr: imx8m: Return error values from LPDDR4 trainingFrieder Schrempf
In cases when the same SPL should run on boards with i.MX8MM, that differ in DDR configuration, it is necessary to try different parameters and check if the training done by the firmware suceeds or not. Therefore we return the DDR training/initialization success to the upper layer in order to be able to retry with different settings if necessary.

2020-01-07mach-imx: bootaux: elf firmware supportIgor Opaniuk
Currently imx-specific bootaux command doesn't support ELF format firmware for Cortex-M4 core. This patches introduces a PoC implementation of handling elf firmware (load_elf_image_phdr() was copy-pasted from elf.c just for PoC). ELF64 binaries isn't supported yet. This has the advantage that the user does not need to know to which address the binary has been linked to. However, in order to handle and load the elf sections to the right address, we need to translate the Cortex-M4 core memory addresses to primary/host CPU memory addresses (Cortex A7/A9 cores). This allows to boot firmwares from any location with just using bootaux, e.g.: > tftp ${loadaddr} hello_world.elf && bootaux ${loadaddr} Similar translation table can be found in the Linux remoteproc driver [1].

2020-01-03arm: mach-k3: Enable WA for R5F deadlockLokesh Vutla
On K3 devices there are 2 conditions where R5F can deadlock: 1.When software is performing series of store operations to cacheable write back/write allocate memory region and later on software execute barrier operation (DSB or DMB). R5F may hang at the barrier instruction. 2.When software is performing a mix of load and store operations within a tight loop and store operations are all writing to cacheable write back/write allocates memory regions, R5F may hang at one of the load instruction. To avoid the above two conditions disable linefill optimization inside Cortex R5F which will make R5F to only issue up to 2 cache line fills at any point of time.
