27117b2024 mx7ulp: Add HAB boot support
Add CAAM clock functions, SEC_CONFIG[1] fuse checking, and default CSF
size for HAB support boot on mx7ulp.

Users need to uncomment the CONFIG_SECURE_BOOT in mx7ulp_evk.h to build
secure uboot.

c40d612b1a serial: lpuart: restructure lpuart driver
Drop CONFIG_LPUART_32B_REG.
Move the register structure to a common file include/fsl_lpuart.h
Define lpuart_serial_platdata structure which includes the reg base and flags.
For 32Bit register access, use lpuart_read32/lpuart_write32 which handles
big/little endian.
For 8Bit register access, still use the orignal code.

Add the imx_rgpio2p driver for Rapid GPIO2P controllers on i.MX7ULP.
Have added all ports on RGPIO2P_0 and RGPIO2P_1.

The configurations CONFIG_IMX_RGPIO2P and CONFIG_DM_GPIO must be set
to y to enable the drivers.

To use the GPIO function, the IBE and OBE needs to set in IOMUXC.
We did not set the bits in driver, but leave them to IOMUXC settings
of the GPIO pins. User should use IMX_GPIO_NR to generate the GPIO number
for gpio APIs access.

3e747197b1 rockchip: rk3188: Add sdram driver
The sdram controller blocks are very similar to the rk3288 in utilizing
memory scheduler, Designware uPCTL and Designware PUBL blocks, only
limited to one bank instead of two.

There are some minimal differences when setting up the ram, so it gets
a separate driver for the rk3188 but reuses the driver structs, as there
is no need to define the same again.

More optimization can happen when the modelling of the controller parts
in the dts actually follow the hardware layout hopefully at some point
in the future.

compilation of the bootrom hook-code as well as enabling the
behaviour of loading the full U-Boot via the boot.

New added socs may always need the bootrom code, while still
being able to decide between loading U-Boot regularly or via
the bootrom separately.

So move the compilation of the bootrom code to a hidden option
that gets selected by ROCKCHIP_SPL_BACK_TO_BROM, but can also
be selected by other parts.

214a17e61d STiH410: Add STi serial driver
This patch adds support to ASC (asynchronous serial controller)
driver, which is basically a standard serial driver. This IP
is common across other STMicroelectronics SoCs

622bad103b armv7m: Add SysTick timer driver
The SysTick is a 24-bit down counter that is found on all ARM Cortex
M3, M4, M7 devices and is always located at a fixed address.

The number of reference clock ticks that correspond to 10ms is normally
defined in the SysTick Calibration register's TENMS field. However, on some
devices this is wrong, so this driver allows the clock rate to be defined
using CONFIG_SYS_HZ_CLOCK.

19a75b8cf8 arm: omap3: Bring back ARM errata workaround 725233
The workaround for ARM errata 725233 had been lost since
commit 45bf05854b (armv7: adapt omap3 to the new cache
maintenance framework). Bring it back in order to avoid
very difficult to reproduce, but actually encountered in
the wild CPU deadlocks when running software rendered
X11 desktop on OMAP3530 hardware.
