The LLVM ld.lld linker uses a different symbol type for __bss_start,
resulting in the calculation of KBSS_SZ to be thrown off. Up until now,
this has gone unnoticed as it only affects the appended DTB case, but
pending changes for ARM in the way the decompressed kernel is cleaned
from the caches has uncovered this problem.
On a ld.lld build:
$ nm vmlinux |grep bss_
c1c22034 D __bss_start
c1c86e98 B __bss_stop
resulting in
$ readelf -s arch/arm/boot/compressed/vmlinux | grep bss_size
433: c1c86e98 0 NOTYPE GLOBAL DEFAULT ABS _kernel_bss_size
which is obviously incorrect, and may cause the cache clean to access
unmapped memory, or cause the size calculation to wrap, resulting in no
cache clean to be performed at all.
Fix this by updating the sed regex to take D type symbols into account.

changes in the past five years or more.
I made a list and asked around which ones are no longer in use, and
received confirmation about six ARM platforms and the TI C6x
architecture that have all reached the end of their life upstream,
with no known users remaining:
- efm32 - added in 2011, first Cortex-M, no notable changes after 2013
- picoxcell - added in 2011, abandoned after 2012 acquisition
- prima2 - added in 20111, no notable changes since 2015
- tango - added in 2015, sporadic changes until 2017, but abandoned
- u300 - added in 2009, no notable changes since 2013
- zx - added in 2015 for both 32, 2017 for 64 bit, no notable changes
- arch/c6x - added in 2011, but work stalled soon after that
A number of other platforms on the original list turned out to still
have users. In some cases there are out-of-tree patches and users that
plan to contribute them in the future, in other cases the code is
complete and works reliably"

The Ebang EBAZ4205 is a simple board based on the Xilinx Zynq-7000 SoC.
Its features are:
- one serial port
- 256 MB RAM
- 128 MB NAND flash
- SDcard slot
- IP101GA 10/100 Mbit Ethernet PHY (connected to PL IOs)
- two LEDs (connected to PL IOs)
- one Push Button (connect to PL IOs)
- (optional) RTC
- (optional) Input voltage supervisor
The NAND flash is not supported in mainline linux yet. Unfortunately,
the PHY is connected via the PL, thus for working ethernet the FPGA has
to be configured. Also, depending on the board variant, the PHY has no
external crystal and its clock needs to be driven by the PL. FCLK3 is
used for this and is kept enabled.

Actions Semi ARM DT changes for v5.12:
Updates to the existing S500 ARM SoC. Support has been added for CMU (Clock
Management Unit), Reset controller, DMA, Pinctrl/GPIO, MMC, I2C and SIRQ
(interrupt controller). Since the CMU support is added, the dummy fixed clock
used for the UART controller has been removed for all S500 based boards and
proper UART clock from CMU is used.
Added uSD support and I2C pinctrl configuration for Roseapplepi board based on
S500 SoC. This will make the board boot mainline with a distro from uSD card.
The I2C pinctrl config is added specifically for the PMIC which is currently
under review.

The 32-bit Amlogic Meson SoCs embed an ARC processor in the Always-On
power domain which is typically used for managing system suspend. The
memory for this ARC core is taken from the AHB SRAM area. Depending on
the actual SoC a different ARC core is used:
- Meson6 and earlier: some ARCv1 ISA based core (probably an ARC625)
- Meson8 and later: an ARC EM4 (ARCv2 ISA) based core
Add the device-tree node for this remote-processor along with the
required SRAM sections, clocks and reset-lines. Also use the
SoC-specific compatible string to manage any differences (should
they exist).
On Meson8, Meson8b and Meson8m2 the "secbus2" IO region is needed as
some bits need to be programmed there. Add this IO region for those
SoCs as well.

This reverts commit c17e9377aa.
The lpc32xx clock driver is not able to actually change the PLL rate as
this would require reparenting ARM_CLK, DDRAM_CLK, PERIPH_CLK to SYSCLK,
then stop the PLL, update the register, restart the PLL and wait for the
PLL to lock and finally reparent ARM_CLK, DDRAM_CLK, PERIPH_CLK to HCLK
PLL.
Currently, the HCLK driver simply updates the registers but this has no
real effect and all the clock rate calculation end up being wrong. This is
especially annoying for the peripheral (e.g. UARTs, I2C, SPI).
