      console: Implement pre-console buffer · 9558b48a
      Graeme Russ authored
      Allow redirection of console output prior to console initialisation to a
      temporary buffer.
      
      To enable this functionality, the board (or arch) must define:
       - CONFIG_PRE_CONSOLE_BUFFER - Enable pre-console buffer
       - CONFIG_PRE_CON_BUF_ADDR - Base address of pre-console buffer
       - CONFIG_PRE_CON_BUF_SZ - Size of pre-console buffer (in bytes)
      
      The pre-console buffer will buffer the last CONFIG_PRE_CON_BUF_SZ bytes
      Any earlier characters are silently dropped.

      powerpc/85xx: introduce and document CONFIG_SYS_CCSRBAR macros · e46fedfe
      Timur Tabi authored
      Introduce the CONFIG_SYS_CCSRBAR_PHYS_HIGH and CONFIG_SYS_CCSRBAR_PHYS_LOW
      macros, which contain the high and low portions of CONFIG_SYS_CCSRBAR_PHYS.
      This is necessary for the assembly-language code that relocates CCSR, since
      the assembler does not understand 64-bit constants.
      
      CONFIG_SYS_CCSRBAR_PHYS is automatically defined from the
      CONFIG_SYS_CCSRBAR_PHYS_HIGH and CONFIG_SYS_CCSRBAR_PHYS_LOW macros, so it
      should not be defined in a board header file.  Similarly,
      CONFIG_SYS_CCSRBAR_DEFAULT is defined for each SOC in config_mpc85xx.h, so
      it should also not be defined in the board header file.
      
      CONFIG_SYS_CCSR_DO_NOT_RELOCATE is a "short-cut" macro that guarantees that
      CONFIG_SYS_CCSRBAR_PHYS is set to the same value as CONFIG_SYS_CCSRBAR_DEFAULT,
      and so CCSR will not be relocated.
      
      Since CONFIG_SYS_CCSRBAR_DEFAULT is locked to a fixed value, multi-stage U-Boot
      builds (e.g. NAND) are required to relocate CCSR only during the last stage
      (i.e. the "real" U-Boot).  All other stages should define
      CONFIG_SYS_CCSR_DO_NOT_RELOCATE to ensure that CCSR is not relocated.
      
      README is updated with descriptions of all the CONFIG_SYS_CCSRBAR_xxx macros.

      armv7: cache maintenance operations for armv7 · 2c451f78
      Aneesh V authored
      - Add a framework for layered cache maintenance
      	- separate out SOC specific outer cache maintenance from
      	  maintenance of caches known to CPU
      
      - Add generic ARMv7 cache maintenance operations that affect all
        caches known to ARMv7 CPUs. For instance in Cortex-A8 these
        opertions will affect both L1 and L2 caches. In Cortex-A9
        these will affect only L1 cache
      
      - D-cache operations supported:
      	- Invalidate entire D-cache
      	- Invalidate D-cache range
      	- Flush(clean & invalidate) entire D-cache
      	- Flush D-cache range
      - I-cache operations supported:
      	- Invalidate entire I-cache
      
      - Add maintenance functions for TLB, branch predictor array etc.
      
      - Enable -march=armv7-a so that armv7 assembly instructions can be
        used

      NAND: Add 16bit NAND support for the NDFC · eced4626
      Alex Waterman authored
      This patch adds support for 16 bit NAND devices attached to the
      NDFC on ppc4xx processors. Two config entries were added:
      
        CONFIG_SYS_NDFC_16        - Setting this tells the NDFC that a
      			      16 bit device is attached.
        CONFIG_SYS_NDFC_EBC0_CFG  - This is for the External Bus
      			      Controller configuration register.
      
      Also, a new ndfc_read_byte() function was added which does not
      first convert the data to little endian.
      
      The NAND SPL was also modified to do 16bit bad block testing
      when a 16 bit chip is being used.

      powerpc/fsl_pci: Fix device tree fixups for newer platforms · 8f29084a
      Kumar Gala authored
      We assumed that only a small set of compatiable strings would be needed
      to find the PCIe device tree nodes to be fixed up.  However on newer
      platforms the simple rules no longer work.  We need to allow specifying
      the PCIe compatiable string for each individual SoC.
      
      We introduce CONFIG_SYS_FSL_PCIE_COMPAT for this purpose and set it if
      the default isn't sufficient.

      cmd_ide: enhance new feature "CONFIG_IDE_AHB" · 0abddf82
      Macpaul Lin authored
      Although most IDE controller is designed to be connected to PCI bridge,
      there are still some IDE controller support AHB interface for SoC design.
      
      The driver implementation of these IDE-AHB controllers differ from other
      IDE-PCI controller, some additional registers and commands access is required
      during CMD/DATA I/O. Hence a configuration "CONFIG_IDE_AHB" in cmd_ide.c is
      required to be defined to support these kinds of SoC controllers. Such as
      Faraday's FTIDE020 series and Global Unichip's UINF-0301.

      powerpc: use 'video-mode' environment variable to configure DIU · ba8e76bd
      Timur Tabi authored
      Use the 'video-mode' environment variable (for Freescale chips that have a
      DIU display controller) to designate the full video configuration.  Previously,
      the DIU driver used the 'monitor' variable, and it was used only to determine
      the output video port.
      
      The old definition of the "monitor" environment variable only determines
      which video port to use for output.  This variable was set to a number (0,
      1, or sometimes 2) to specify a DVI, LVDS, or Dual-LVDS port.  The
      resolution was hard-coded into board-specific code.  The Linux command-line
      arguments needed to be hard-coded to the proper video definition string.

      common: add a grepenv command · a000b795
      Kim Phillips authored
      u-boot environments, esp. when boards are shared across multiple
      users, can get pretty large and time consuming to visually parse.
      The grepenv command this patch adds can be used in lieu of printenv
      to facilitate searching.  grepenv works like printenv but limits
      its output only to environment strings (variable name and value
      pairs) that match the user specified substring.
      
      the following examples are on a board with a 5313 byte environment
      that spans multiple screen pages:
      
      Example 1:  summarize ethernet configuration:
      
      => grepenv eth TSEC
      etact=FM1@DTSEC2
      eth=FM1@DTSEC4
      ethact=FM1@DTSEC2
      eth1addr=00:E0:0C:00:8b:01
      eth2addr=00:E0:0C:00:8b:02
      eth3addr=00:E0:0C:00:8b:03
      eth4addr=00:E0:0C:00:8b:04
      eth5addr=00:E0:0C:00:8b:05
      eth6addr=00:E0:0C:00:8b:06
      eth7addr=00:E0:0C:00:8b:07
      eth8addr=00:E0:0C:00:8b:08
      eth9addr=00:E0:0C:00:8b:09
      ethaddr=00:E0:0C:00:8b:00
      netdev=eth0
      uprcw=setenv ethact $eth;setenv filename p4080ds/R_PPSXX_0xe/rcw_0xe_2sgmii_rev2_high.bin;setenv start 0xe8000000;protect off all;run upimage;protect on all

      =>
      
      Example 2: detect unused env vars:
      
      => grepenv etact
      etact=FM1@DTSEC2
      =>
      
      Example 3: reveal hardcoded variables; e.g., for fdtaddr:
      
      => grepenv fdtaddr
      fdtaddr=c00000
      nfsboot=setenv bootargs root=/dev/nfs rw nfsroot=$serverip:$rootpath ip=$ipaddr:$serverip:$gatewayip:$netmask:$hostname:$netdev:off console=$consoledev,$baudrate $othbootargs;tftp $loadaddr $bootfile;tftp $fdtaddr $fdtfile;bootm $loadaddr - $fdtaddr
      ramboot=setenv bootargs root=/dev/ram rw console=$consoledev,$baudrate $othbootargs;tftp $ramdiskaddr $ramdiskfile;tftp $loadaddr $bootfile;tftp $fdtaddr $fdtfile;bootm $loadaddr $ramdiskaddr $fdtaddr
      => grep $fdtaddr
      fdtaddr=c00000
      my_boot=bootm 0x40000000 0x41000000 0x00c00000
      my_dtb=tftp 0x00c00000 $prefix/p4080ds.dtb

      =>
      
      This patch also enables the grepenv command by default on
      corenet_ds based boards (and repositions the DHCP command
      entry to keep the list sorted).

      This patch move the kirkwood only driver definitoin in mv-common to
