f605079041 powerpc/mpc85xx: Add T1024/T1023 SoC support
Add support for Freescale T1024/T1023 SoC.

The T1024 SoC includes the following function and features:
- Two 64-bit Power architecture e5500 cores, up to 1.4GHz
- private 256KB L2 cache each core and shared 256KB CoreNet platform cache (CPC)
- 32-/64-bit DDR3L/DDR4 SDRAM memory controller with ECC and interleaving support
- Data Path Acceleration Architecture (DPAA) incorporating acceleration
- Four MAC for 1G/2.5G/10G network interfaces (RGMII, SGMII, QSGMII, XFI)
- High-speed peripheral interfaces
  - Three PCI Express 2.0 controllers
- Additional peripheral interfaces
  - One SATA 2.0 controller
  - Two USB 2.0 controllers with integrated PHY
  - Enhanced secure digital host controller (SD/eSDHC/eMMC)
  - Enhanced serial peripheral interface (eSPI)
  - Four I2C controllers
  - Four 2-pin UARTs or two 4-pin UARTs
  - Integrated Flash Controller supporting NAND and NOR flash
- Two 8-channel DMA engines
- Multicore programmable interrupt controller (PIC)
- LCD interface (DIU) with 12 bit dual data rate
- QUICC Engine block supporting TDM, HDLC, and UART
- Deep Sleep power implementaion (wakeup from GPIO/Timer/Ethernet/USB)
- Support for hardware virtualization and partitioning enforcement
- QorIQ Platform's Trust Architecture 2.0

Differences between T1024 and T1023:
  Feature         T1024  T1023
  QUICC Engine:   yes    no
  DIU:            yes    no
  Deep Sleep:     yes    no
  I2C controller: 4      3
  DDR:            64-bit 32-bit
  IFC:            32-bit 28-bit

b24f6d401c powerpc/b4860qds: add workaround for XFI
XFI does not work stable on current board, it's due to heat sink issue,
to make it work stable the board needs additional heat sink, enable two
XFI lanes only. Right now we do not have such an erratum for the issue,
so use a define CONFIG_SYS_FSL_B4860QDS_XFI_ERR to identify it.
The workaround will only be used in XFI protocols and only if the
hwconfig indicates that XFI is prefered.

A new VSC3308 config function is used instead of re-use the original
function, to avoid making the function complex and ugly.

To support interactive DDR debugger, cli_simple.o, cli.o, cli_readline.o,

drivers/ddr/fsl/interactive.c.

In current common/Makefile, the above .o files are only produced when
CONFIG_SPL_BUILD is disabled.

For LS102xA, interactive DDR debugger is needed in SD/NAND boot too, and
I enabled CONFIG_FSL_DDR_INTERACTIVE. But according to the current
common/Makfile, all the above .o files are not produced in SPL part
because CONFIG_SPL_BUILD is enabled in SPL part, the following error
will be shown,

drivers/ddr/fsl/built-in.o: In function `fsl_ddr_interactive':
/home/wangh/layerscape/u-boot/drivers/ddr/fsl/interactive.c:1871:

undefined reference to `cli_simple_parse_line'
make[1]: *** [spl/u-boot-spl] Error 1

So this patch fixed this issue and the above .o files will be produced

fb384c4720 mtd: nand: omap_gpmc: Always use ready/busy pin
The functions to detect the state of the ready / busy signal is already
available but only used in the SPL case. Lets use it always, also for the
main U-Boot. As all boards should have this HW connection.

Testing on Siemens Draco (am335x) showed a small perfomance gain by using
this ready pin to detect the NAND chip state. Here the values tested on
Draco with Hynix 4GBit NAND:

Without NAND ready pin:

U-Boot# time nand read 80400000 0 400000

NAND read: device 0 offset 0x0, size 0x400000
4194304 bytes read: OK

time: 2.947 seconds, 2947 ticks

With NAND ready pin:

U-Boot# time nand read 80400000 0 400000

NAND read: device 0 offset 0x0, size 0x400000
4194304 bytes read: OK

time: 2.795 seconds, 2795 ticks

So an increase of approx. 5%.

(e.g. MMC2 power can be controlled by another LDO than VMMC2).
This delegates TWL4030 MMC power initializations to board-specific functions,
that may still call twl4030_power_mmc_init for the default behavior.

7a7eb983a4 mmc: sh_mmcif: Change maximum and minimum value of MMC clock
Maximum value and the minimum value of clock for sh_mmcif instead by
base of MMC clock. This removes fixed clock, make the changes to be calculated
according to environment.

d3a22419cf arm: rmobile: rcar: Add structure for infomation of module control register
The infomation of module control register for R-Car ARM SoC (r8a7790, r8a7791,
r8a7793 and r8a7794) are almost the same, they can be combined into one
structure. This provides structure that summarizes infomation of module control
register and default register values.
And this structure is the module control use of the kernel at boot time.
