On iMX8MQ Rev B1, reading from fuse box is not allowed. The
OCOTP_READ_FUSE_DATA register is tied to magic number 0xff0055aa
for chip rev. So u-boot has to disable the fuse sense function for it.Signed-off-by: Ye Li

On i.MX7ULP, the fuse words (except bank 0 and 1) only supports to

This patch adds changes necessary to move functionality present in
PowerPC folders with ARM architectures that have DPAA1 QBMan hardware- Create new board/freescale/common/fsl_portals.c to house shared
device tree fixups for DPAA1 devices with ARM and PowerPC cores
- Add new header file to top includes directory to allow files in
both architectures to grab the function prototypes
- Port inhibit_portals() from PowerPC to ARM. This function is used in
setup to disable interrupts on all QMan and BMan portals. It is
needed because the interrupts are enabled by default for all portals
including unused/uninitialised portals. When the kernel attempts to
go to deep sleep the unused portals prevent it from doing soSigned-off-by: Ahmed Mansour

Like STM32H7, now STM32F4/F7 clock drivers are binded by
MFD stm32_rcc driver.
This also allows to add reset support to STM32F4/F7 SoCs family.
As Reset driver is not part of SPL supported drivers, don't bind it
in case of SPL to avoid that stm32_rcc_bind() returns an error.Signed-off-by: Patrice Chotard

U-Boot widely uses error() as a bit noisier variant of printf().
This macro causes name conflict with the following line in
include/linux/compiler-gcc.h:# define __compiletime_error(message) __attribute__((error(message)))
This prevents us from using __compiletime_error(), and makes it
difficult to fully sync BUILD_BUG macros with Linux. (Notice
Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().)Let's convert error() into now treewide-available pr_err().
Done with the help of Coccinelle, excluing tools/ directory.
The semantic patch I used is as follows:
//
@@@@
-error
+pr_err
(...)

This adds a simple driver for reading the efuse block of the RK3399.
It should be easy enough to add drivers for other devices (e.g. the
RK3328, RK3368, etc.) by passing the device details via driver_data.Unlike the kernel driver (using the nvmem subsystem), we don't expose
the efuse as multiple named cells, but rather as a linear memory that
can be read using misc_read(...).The primary use case (as of today) is the generation of a 'serial#'
(and a 'cpuid#') environment variable for the RK3399-Q7 (Puma)
system-on-module.Note that this adds a debug-only (i.e. only if DEBUG is defined)
command 'rk3399_dump_efuses' that dumps the efuse block's content.
N.B.: The name 'rk3399_dump_efuses' was intentionally chosen to
include a SoC-name (together with a comment in the function) to
remind whoever adds support for additional SoCs that this
function currently makes assumptions regarding the size of the
fuse-box based on the RK3399. The hope is that the function is
adjusted to reflect any changes resulting from generalising the
driver for multiple SoCs and is then renamed.Signed-off-by: Philipp Tomsich

These support the flat device tree. We want to use the dev_read_..()
prefix for functions that support both flat tree and live tree. So rename
the existing functions to avoid confusion.In the end we will have:
1. dev_read_addr...() - works on devices, supports flat/live tree
2. devfdt_get_addr...() - current functions, flat tree only
3. of_get_address() etc. - new functions, live tree onlyAll drivers will be written to use 1. That function will in turn call
either 2 or 3 depending on whether the flat or live tree is in use.Note this involves changing some dead code - the imx_lpi2c.c file.
