Commit 96d2bb952b ("powerpc/mpc85xx: Don't relocate exception vectors")
simplified IVOR initialization a bit too much, failing to use the
post-relocation offset. This doesn't cause a problem with normal NOR
boot, in which both the pre-relocation and post-relocation addresses
are 64 KiB aligned. However, if TEXT_BASE is only 4 KiB aligned, such
as for NAND/SD/etc. boot on some targets, as well as the QEMU target,
the post-relocation address will not be the same in the lower 16 bits,
as reserve_uboot() ensures that the relocation address is always 64
KiB aligned even if the pre-relocation address was not.
Use the GOT to get the proper post-relocation offsets.

U-Boot does not have system calls (the services it exposes to
standalone commands use a different mechanism), so the syscall handler
is dead code. It's also broken code, as it assumes it is located at
0xc00 -- while even before the patch to stop relocating exception
vectors to 0, U-Boot had the syscall at 0x900.
The critical and machine check return paths are never called -- the
regular exception return path is used instead, which works because
xSRR0/1 have already been saved and can be restored via the regular
SRR0/1 (we don't care too much in U-Boot about taking a critical/mcheck
inside another exception prolog/epilog).
Also remove a few other small unused functions.

Booke does not require exception vectors to be located at address zero.
U-Boot was doing so anyway, simply because that's how it had been done
on other PPC. The downside of this is that once the OS is loaded to
address zero, the exception vectors have been overwritten -- which
makes it difficult to diagnose a crash that happens after that point.
The IVOR setup and trap entry code is simplified somewhat as a result.
Also, there is no longer a need to align individual exceptions on 0x100
byte boundaries.

U-Boot has never cared about the type when we get max/min of two
values, but Linux Kernel does. This commit gets min, max, min3, max3
macros synced with the kernel introducing type checks.
Many of references of those macros must be fixed to suppress warnings.
We have two options:
- Use min, max, min3, max3 only when the arguments have the same type
(or add casts to the arguments)
- Use min_t/max_t instead with the appropriate type for the first
argument

However, u-boot needs to know the expected PLL ratio. We put the
ratio in a reserved field RCW[18:23]. U-boot will skip this workaround
if DDR PLL ratio is set, or the reserved field is not set.
Workaround for erratum A007212 applies to selected versions of

Single-source clocking is new feature introduced in T1040.
In this mode, a single differential clock is supplied to the
DIFF_SYSCLK_P/N inputs to the processor, which in turn is
used to supply clocks to the sysclock, ddrclock and usbclock.
So, both ddrclock and syclock are driven by same differential
sysclock in single-source clocking mode whereas in normal clocking
mode, generally separate DDRCLK and SYSCLK pins provides
reference clock for sysclock and ddrclock
DDR_REFCLK_SEL rcw bit is used to determine DDR clock source
-If DDR_REFCLK_SEL rcw bit is 0, then DDR PLLs are driven in
normal clocking mode by DDR_Reference clock
-If DDR_REFCLK_SEL rcw bit is 1, then DDR PLLs are driven in
single source clocking mode by DIFF_SYSCLK
Add code to determine ddrclock based on DDR_REFCLK_SEL rcw bit.

When a board (slave) boots from SRIO/PCIE, it would get the instructions
from a remote board (master) by SRIO/PCIE interface, and the slave's
u-boot image should be built with the
SYS_TEXT_BASE=0xFFF80000;
So the u-boot of the slave should avoid the NOR_BOOT branch at the
booting stage.
For example, when a P2041RDB boots from SRIO/PCIE, it will set TLB
entry 15 from base address "CONFIG_SYS_MONITOR_BASE & 0xffc00000",
and with the 4M size as the boot window in NOR_BOOT branch. Because
the CONFIG_SYS_MONITOR_BASE = CONFIG_SYS_TEXT_BASE = 0xFFF80000, so
the TLB entry will be from base address 0xffc00000 and with 4M size.
Then the u-boot will set TLB entry 14 from base address
"CONFIG_SYS_INIT_RAM_ADDR", and with the 16K size as the initial
stack window. For the P2041RDB platform, the CONFIG_SYS_INIT_RAM_ADDR
= 0xffd00000. So the TLB entry 14 and 15 will be in confliction.
There will be right TLB entries configurations when avoid the
NOR_BOOT branch and set the boot window from 0xfff00000 with 1M
size space.

The BSC9132 is a highly integrated device that targets the evolving
Microcell, Picocell, and Enterprise-Femto base station market subsegments.
The BSC9132 device combines Power Architecture e500 and DSP StarCore SC3850
core technologies with MAPLE-B2P baseband acceleration processing elements
to address the need for a high performance, low cost, integrated solution
that handles all required processing layers without the need for an
external device except for an RF transceiver or, in a Micro base station
configuration, a host device that handles the L3/L4 and handover between
sectors.
The BSC9132 SoC includes the following function and features:
- Power Architecture subsystem including two e500 processors with
512-Kbyte shared L2 cache
- Two StarCore SC3850 DSP subsystems, each with a 512-Kbyte private L2
cache
- 32 Kbyte of shared M3 memory
- The Multi Accelerator Platform Engine for Pico BaseStation Baseband
Processing (MAPLE-B2P)
- Two DDR3/3L memory interfaces with 32-bit data width (40 bits including
ECC), up to 1333 MHz data rate
- Dedicated security engine featuring trusted boot
- Two DMA controllers
- OCNDMA with four bidirectional channels
- SysDMA with sixteen bidirectional channels
- Interfaces
- Four-lane SerDes PHY
- PCI Express controller complies with the PEX Specification-Rev 2.0
- Two Common Public Radio Interface (CPRI) controller lanes
- High-speed USB 2.0 host and device controller with ULPI interface
- Enhanced secure digital (SD/MMC) host controller (eSDHC)
- Antenna interface controller (AIC), supporting four industry
standard JESD207/four custom ADI RF interfaces
- ADI lanes support both full duplex FDD support & half duplex TDD
- Universal Subscriber Identity Module (USIM) interface that
facilitates communication to SIM cards or Eurochip pre-paid phone
cards
- Two DUART, two eSPI, and two I2C controllers
- Integrated Flash memory controller (IFC)

The work-around for erratum A-004580 ("Internal tracking loop can falsely

(pre-boot initialization code, typically attached to the RCW binary).
This is because the work-around is easier to implement in PBI than in
U-Boot itself.
It is still useful, however, for the 'errata' command to tell us whether
the work-around has been applied. For A-004580, we can do this by verifying

There were a number of shared files that were using

several variants (DDR2, DDR3). A recent patchset added
85xx-specific ones to code which was used by 86xx systems.
After reviewing places where these constants were used, and
noting that the type definitions of the pointers assigned to
point to those addresses were the same, the cleanest approach
to fixing this problem was to unify the namespace for the
85xx, 83xx, and 86xx DDR address definitions.

CONFIG_RAMBOOT will need to remain for other use cases, but it doesn't
seem right to overload it for meaning SPL as well as nand_spl does. Even
if it's somewhat appropriate for the main u-boot, the SPL itself isn't
