2022-05-20imx8m: fix reading of DDR4 MR registersRasmus Villemoes
I was trying to employ lpddr4_mr_read() to something similar to what the imx8mm-cl-iot-gate board is doing for auto-detecting the RAM type. However, the version in drivers/ddr/imx/imx8m/ddrphy_utils.c differs from the private one used by that board in how it extracts the byte value, and I was only getting zeroes. Adding a bit of debug printf'ing gives me tmp = 0x00ffff00 tmp = 0x00070700 tmp = 0x00000000 tmp = 0x00101000 and indeed I was expecting a (combined) value of 0xff070010 (0xff being Manufacturer ID for Micron). I can't find any documentation that says how the values are supposed to be read, but clearly the iot-gate definition is the right one, both for its use case as well as my imx8mp-based board. So lift the private definition of lpddr4_mr_read() from the imx8mm-cl-iot-gate board code to ddrphy_utils.c, and add a declaration in the ddr.h header where e.g. get_trained_CDD() is already declared. This has only been compile-tested for the imx8mm-cl-iot-gate board (since I don't have the hardware), but since I've merely moved its definition of lpddr4_mr_read(), I'd be surprised if it changed anything for that board.

2022-05-20ARM: imx: imx31: Introduce and use UART_BASE_ADDR(n)Marek Vasut
Introduce helper macro UART_BASE_ADDR(n), which returns Nth UART base address. Convert all board configurations to this new macro. This is the first step toward switching CONFIG_MXC_UART_BASE to Kconfig. This is a clean up, no functional change. The new macro contains compile-time test to verify N is in suitable range. The test works such that it multiplies constant N by constant double-negation of size of a non-empty structure, i.e. it multiplies constant N by constant 1 in each successful compilation case. The non-empty structure may contain C11 _Static_assert(), make use of this and place the kernel variant of static assert in there, so that it performs the compile-time check for N in the correct range. Note that it is not possible to directly use static_assert in compound statements, hence this convoluted construct.

2022-05-18arm64: zynqmp: Set qspi tx-buswidth to 4Amit Kumar Mahapatra
In all the ZynqMP boards dts files tx-buswidth is by default set to 1. Due to this the framework only issues 1-1-1 write commands to the GQSPI driver. But the GQSPI controller is capable of handling 1-4-4 write commands, so updated the tx-buswidth to 4 in ZynqMP boards dts files. This would enable the spi-nor framework to issue 1-4-4 write commands instead of 1-1-1.

2022-05-18arm64: zynqmp: Fix split mode reset functionalityNeal Frager
This patch fixes two issues in the set_r5_reset function. 1. When in split mode, the lpd_amba_rst bit should only be set when both r5 cpu cores are in reset. Otherwise, if one r5 core is still running, setting the lpd_amba_rst bit will cause an error for the running core. The set_r5_reset function has been modified to check if the other r5 core is still running before setting the lpd_amba_rst bit. 2. The cpu_disable function was always assuming that the r5 cores are in split mode when resetting either core 4 or 5. This is incorrect for lockstep functionality. This patch adds a function check_r5_mode to handle the cpu_disable function correctly for the r5 cores by checking the mode and handling the reset appropriately.
