Most predefined TLB tables don't have memory coherence bit set for
SDRAM. This wasn't an issue before invalidate_dcache_range() function
was enabled. Without the coherence bit, dcache invalidation doesn't
automatically flush the cache. The coherence bit is already set when
dynamic TLB table is used. For some boards with different SPL boot
method, or with legacy fixed setting, this bit needs to be set in
TLB files.

Add support of 2 stage NAND boot loader using SPL framework.
here, PBL initialise the internal SRAM and copy SPL(160KB). This further
initialise DDR using SPD and environment and copy u-boot(768 KB) from NAND to DDR.
Finally SPL transer control to u-boot.
Initialise/create followings required for SPL framework
- Add spl.c which defines board_init_f, board_init_r
- update tlb and ddr accordingly

When a b4860qds board boots from SRIO or PCIE, it needs to finish these
processes:
1. Set all the cores in holdoff status.
2. Set the boot location to one PCIE or SRIO interface by RCW.
3. Set a specific TLB entry for the boot process.
4. Set a LAW entry with the TargetID of one PCIE or SRIO for the boot.
5. Set a specific TLB entry in order to fetch ucode and ENV from
master.
6. Set a LAW entry with the TargetID one of the PCIE ports for
ucode and ENV.
7. Slave's u-boot image should be generated specifically by
make xxxx_SRIO_PCIE_BOOT_config.
This will set SYS_TEXT_BASE=0xFFF80000 and other configurations.
For more information about the feature of Boot from SRIO/PCIE, please
refer to the document doc/README.srio-pcie-boot-corenet.

Add the tlb entries based on the configuration of the SRIO interfaces.
Every SRIO interface has 256M space:
#define CONFIG_SYS_SRIO1_MEM_VIRT 0xa0000000
#define CONFIG_SYS_SRIO1_MEM_PHYS 0xc20000000ull

B4860QDS is a high-performance computing evaluation, development and
test platform supporting the B4860 QorIQ Power Architecture processor.
B4860QDS Overview
------------------
- DDRC1: Ten separate DDR3 parts of 16-bit to support 72-bit (ECC) at 1866MT/s,
ECC, 4 GB of memory in two ranks of 2 GB.
- DDRC2: Five separate DDR3 parts of 16-bit to support 72-bit (ECC) at 1866MT/s, ECC, 2 GB of memory. Single rank.
- SerDes 1 multiplexing: Two Vitesse (transmit and receive path) cross-point
16x16 switch VSC3316
- SerDes 2 multiplexing: Two Vitesse (transmit and receive path) cross-point
8x8 switch VSC3308
- USB 2.0 ULPI PHY USB3315 by SMSC supports USB port in host mode.
- B4860 UART port is available over USB-to-UART translator USB2SER or over
RS232 flat cable.
- A Vitesse dual SGMII phy VSC8662 links the B4860 SGMII lines to 2xRJ-45 copper
connectors for Stand-alone mode and to the 1000Base-X over AMC MicroTCA
connector ports 0 and 2 for AMC mode.
- The B4860 configuration may be loaded from nine bits coded reset
configuration reset source. The RCW source is set by appropriate
DIP-switches:
- 16-bit NOR Flash / PROMJet
- QIXIS 8-bit NOR Flash Emulator
- 8-bit NAND Flash
- 24-bit SPI Flash
- Long address I2C EEPROM
- Available debug interfaces are:
- On-board eCWTAP controller with ETH and USB I/F
- JTAG/COP 16-pin header for any external TAP controller
- External JTAG source over AMC to support B2B configuration
- 70-pin Aurora debug connector
- QIXIS (FPGA) logic:
- 2 KB internal memory space including
- IDT840NT4 clock synthesizer provides B4860 essential clocks : SYSCLK,
DDRCLK1, 2 and RTCCLK.
- Two 8T49N222A SerDes ref clock devices support two SerDes port clocks
- total four refclk, including CPRI clock scheme
