The RTL9300 has a broken R4K MIPS timer interrupt, however, the
R4K clocksource works. We replace the RTL9300 timer with a
Clock Event Timer (CEVT), which is VSMP aware and can be instantiated
as part of brining a VSMTP cpu up instead of the R4K CEVT source.
For this we place the RTL9300 CEVT timer in arch/mips/kernel
together with other MIPS CEVT timers, initialize the SoC IRQs
from a modified smp-mt.c and instantiate each timer as part
of the MIPS time setup in arch/mips/include/asm/time.h instead
of the R4K CEVT, similarly as is done by other MIPS CEVT timers.

Setting bits 20 and 23 in a u16 is obviously wrong.
According to https://www.svanheule.net/realtek/cypress/cputag
cpu_tag[2] starts at bit 48 in the cpu-tag structure, so
bit 43 is bit 5 in cpu_tag[2] and bit 40 is bit 8 in
cpu_tag[2].

The GS1900-48 is a 48 + 2 port Gigabit L2 switch with 48 gigabit ports.
Hardware:
RTL8393M SoC
Macronix MX25l12805D (16MB flash)
128MB RAM
6 * RTL8218B external PHY
2 * RTL8231 GPIO extenders to control the port LEDs, system LED and
Reset button
2 Uplink ports are SFP cages which support 1000 Base-X mini GBIC modules.
Power is supplied via a 230 volt mains connector.
The board has a hard reset switch SW1, which is is not reachable from the outside.
J4 provides a 12V RS232 serial connector which is connected through U8 to
the 3.3V UART of the RTL8393. Conversion is done by U8, a SIPEX 3232EC.
To connect to the UART, wires can be soldered to R603 (TX) and R602 (RX).
Installation:
Install the squashfs image via Realtek's original Web-Interface.

Update the IRQ configuration to work with the new rtl-intc controller.
Also change all KSEG1 addresses in reg = <> of the devics to physical

Use the new gpio-otto controller instead of the legacy driver.

The EEPROMs on SFP modules are compatible both to I2C as well
as SMBus. However, the kernel so far only supports I2C
access. We add SMBus access routines, because the I2C driver
for the RTL9300 HW only supports that protocol. At the same
time we disable I2C access to PHYs on SFP modules as otherwise
detection of any SFP module would fail. This is not in any
way problematic at this point in time since the RTL93XX
platform so far does not support PHYs on SFP modules.

The RTL9300/RTL9310 I2C controllers have support for 2 independent I2C
masters, each with a fixed SCL pin, that cannot be changed. Each of these
masters can use 8 (RTL9300) or 16 (RTL9310) different pins for SDA.
This multiplexer directly controls the two masters and their shared
IO configuration registers to allow multiplexing between any of these
busses. The two masters cannot be used in parallel as the multiplex
is protected by a standard multiplex lock.

The controller implements the SMBus protocol for SMBus transfers
over an I2C bus. The driver supports selecting one of the 2 possible
SCL pins and any of the 8 possible SDA pins. Bus speeds of
100kHz (standard speed) and 400kHz (high speed I2C) are supported.

For sysupgrade on NAND/UBI devices there is the U-Boot environment
variable rootfs_data_max which can be used to limit the size of the
rootfs_data volume created on sysupgrade.
This stopped working reliable with recent kernels, probably due to a
race condition when reading the number of free erase blocks from sysfs
just after removing a volume.
Change the script to just try creating rootfs_data with the desired
size and retry with maximum size in case that fails. Hence calculating
the available size in the script can be dropped which works around the
problem.

Feeds are shallow cloned by default, resulting in an incomplete Git log

It's reported that current memory detection code occasionally detects
larger memory under some bootloaders.
Current memory detection code tests whether address space wraps around
on KSEG0, which is unreliable because it's cached.
Rewrite memory size detection to perform the same test on KSEG1 instead.
While at it, this patch also does the following two things:
1. use a fixed pattern instead of a random function pointer as the magic
value.
2. add an additional memory write and a second comparison as part of the
test to prevent possible smaller memory detection result due to
leftover values in memory.
