Subject: powerpc: No need to use dot symbols when branching to a function

binutils is smart enough to know that a branch to a function
descriptor is actually a branch to the functions text address.

Alan tells me that binutils has been doing this for 9 years.

Subject: powerpc/boot: Use a common prom_args struct in oflib
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch fixes warnings when the wrapper is compiled in 64bit and
updates the boot wrapper code related to prom to converge with the
kernel code in prom_init. This should make the review of changes easier.

The kernel has a different number of possible arguments (10) when
entering prom. There does not seem to be any good reason to have
12 in the wrapper, so the patch changes this value to args[10] in
the prom_args struct.

This is a work around. The definite solution would be to define the
phandle typedef as a u32, as in the kernel, but this would break the
device tree ops API.

Let it be for the moment.

These are not the most efficient versions of swab but the wrapper does
not do much byte swapping. On a big endian cpu, these routines are
a no-op.

It could certainly be improved using Elf macros and byteswapping
routines, but the initial version of the code is organised to be a
single file program with limited dependencies. yaboot is the same.

Please scream if you want a total rewrite.

Subject: powerpc/boot: Define a routine to enter prom
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch defines a 'prom' routine similar to 'enter_prom' in the
kernel.

The difference is in the MSR which is built before entering prom. Big
endian order is enforced as in the kernel but 32bit mode is not. It
prepares ground for the next patches which will introduce Little endian
order.

Subject: powerpc/boot: Modify entry point for 64bit
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch adds support a 64bit wrapper entry point. As in 32bit, the
entry point does its own relocation and can be loaded at any address
by the firmware.

Subject: powerpc/boot: Add a global entry point for pseries
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When entering the boot wrapper in little endian, we will need to fix
the endian order using a fixup trampoline like in the kernel. This
patch overrides the _zimage_start entry point for this purpose.

Subject: powerpc/boot: Add support for 64bit little endian wrapper
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The code is only slightly modified : entry points now use the
FIXUP_ENDIAN trampoline to switch endian order. The 32bit wrapper
is kept for big endian kernels and 64bit is enforced for little
endian kernels with a PPC64_BOOT_WRAPPER config option.

The linker script is generated using the kernel preprocessor flags
to make use of the CONFIG_* definitions and the wrapper script is
modified to take into account the new elf64ppc format.

Finally, the zImage file is compiled as a position independent
executable (-pie) which makes it loadable at any address by the
firmware.

Subject: powerpc: Added PCI MSI support using the HSTA module

The PPC476GTR SoC supports message signalled interrupts (MSI) by writing
to special addresses within the High Speed Transfer Assist (HSTA) module.

This patch adds support for PCI MSI with a new system device. The DMA
window is also updated to allow access to the entire 42-bit address range
to allow PCI devices write access to the HSTA module.

Subject: powerpc/mpc85xx: add support for Keymile's kmcoge4 board

This patch introduces the support for Keymile's kmcoge4 board which is
the internal reference design for boards based on Freescale's
P2040/P2041 SoCs. This internal reference design is named kmp204x.

The peripherals used on this board are:
- SPI NOR Flash as bootloader medium
- NAND Flash with a ubi partition
- 2 PCIe busses (hosts 1 and 3)
- 3 FMAN Ethernet devices (FMAN1 DTSEC1/2/5)
- 4 Local Bus windows, with one dedicated to the QRIO reset/power mgmt
  CPLD
- 2 I2C busses
- last but not least, the mandatory serial port

The patch also adds a defconfig file for this reference design that is
necessary because of the lowmem option that must be set higher due to
the number of PCIe devices with big ioremapped mem ranges on the boad.

processor cores with high-performance data path acceleration architecture
and network peripheral interfaces required for networking & telecommunications.

T1042 personality is a reduced personality of T1040 without Integrated 8-port
Gigabit Ethernet switch.

The T1040/T1042 SoC includes the following function and features:

 - Four e5500 cores, each with a private 256 KB L2 cache
 - 256 KB shared L3 CoreNet platform cache (CPC)
 - Interconnect CoreNet platform
 - 32-/64-bit DDR3L/DDR4 SDRAM memory controller with ECC and interleaving
   support
 - Data Path Acceleration Architecture (DPAA) incorporating acceleration
 for the following functions:
    -  Packet parsing, classification, and distribution
    -  Queue management for scheduling, packet sequencing, and congestion
    	management
    -  Cryptography Acceleration (SEC 5.0)
    - RegEx Pattern Matching Acceleration (PME 2.2)
    - IEEE Std 1588 support
    - Hardware buffer management for buffer allocation and deallocation
 - Ethernet interfaces
    - Integrated 8-port Gigabit Ethernet switch (T1040 only)
    - Four 1 Gbps Ethernet controllers
 - Two RGMII interfaces or one RGMII and one MII interfaces
 - High speed peripheral interfaces
   - Four PCI Express 2.0 controllers running at up to 5 GHz
   - Two SATA controllers supporting 1.5 and 3.0 Gb/s operation
   - Upto two QSGMII interface
   - Upto six SGMII interface supporting 1000 Mbps
   - One SGMII interface supporting upto 2500 Mbps
 - Additional peripheral interfaces
   - Two USB 2.0 controllers with integrated PHY
   - SD/eSDHC/eMMC
   -  eSPI controller
   - Four I2C controllers
   - Four UARTs
   - Four GPIO controllers
   - Integrated flash controller (IFC)
   - Change this to  LCD/ HDMI interface (DIU) with 12 bit dual data rate
   - TDM interface
 - Multicore programmable interrupt controller (PIC)
 - Two 8-channel DMA engines
 - Single source clocking implementation
 - Deep Sleep power implementaion (wakeup from GPIO/Timer/Ethernet/USB)
