      powerpc/mpc8536ds: Add eSPI support for MPC8536DS · ae2044d8
      Xie Xiaobo authored 
      
1. The SD_DATA[4:7] signals are shared with the SPI chip selects on 8536DS,
   so don't set MPC85xx_PMUXCR_SD_DATA that config eSDHC data bus-width
   to 4-bit and enable SPI signals.
2. Add eSPI controller and SPI-FLASH definition.

      powerpc/mpc86xx: Disable translation for BAT setup · 1605cc9e
      Becky Bruce authored 
      
We really shouldn't be overwriting bat registers with translation enabled,
especially when we're executing code using one of them for translating
the current instruction stream.  Instead, disable address translation
while doing the final BAT setup.

In order to do this, setup_bats has to move back to asm code, because we
require translation to be enabled to have a stack for C code.  The yucky
thing about that is that the assembler doesn't like ULL so we have to
switch to using HIGH/LOW pairs for physical addresses that are > 32 bits
in length.

      powerpc/85xx: fix null pointer dereference when init the SGMII TBI PHY · 30381716
      Timur Tabi authored 
      
Function dtsec_configure_serdes() needs to know where the TBI PHY registers
are in order to configure SGMII for proper SerDes operation.

During SGMII initialzation, fm_eth_init_mac() passing NULL for 'phyregs'
when it called init_dtsec(), because it was believed that phyregs was not
used.  In fact, it is used by dtsec_configure_serdes() to configure the TBI
PHY registers.

We also need to define the PHY registers in struct fm_mdio.

      powerpc/8xxx: Add support for interactive DDR programming interface · 6f5e1dc5
      York Sun authored 
      
Interactive DDR debugging provides a user interface to view and modify SPD,
DIMM parameters, board options and DDR controller registers before DDR is
initialized. With this feature, developers can fine-tune DDR for board
bringup and other debugging without frequently having to reprogram the flash.

To enable this feature, define CONFIG_FSL_DDR_INTERACTIVE in board header
file and set an environment variable to activate it. Syntax:

setenv ddr_interactive on

After reset, U-boot prompts before initializing DDR controllers
FSL DDR>

The available commands are
print      print SPD and intermediate computed data
reset      reboot machine
recompute  reload SPD and options to default and recompute regs
edit       modify spd, parameter, or option
compute    recompute registers from current next_step to end
next_step  shows current next_step
help       this message
go         program the memory controller and continue with u-boot

The first command should be "compute", which reads data from DIMM SPDs and
board options, performs the calculation then stops before setting DDR
controller. A user can use "print" and "edit" commands to view and modify
anything. "Go" picks up from current step with any modification and
compltes the calculation then enables the DDR controller to continue u-boot.
"Recompute" does it over from fresh reading.

      net: drop !NET_MULTI code · e2a53458
      Mike Frysinger authored 
      
This is long over due.  All but two net drivers have been converted, but
those have now been dropped.

The only thing left to do is actually delete all references to NET_MULTI
and code that is compiled when that is not defined.  So here we scrub the
core code.

      image: push default arch values to arch headers · 476af299

This pushes the ugly duplicated arch ifdef lists we maintain in various
image related files out to the arch headers themselves.

      POST: add post_log_res field for post results in global data · 79843950
      Valentin Longchamp authored 
      
The current post_log_word in global data is currently split into 2x
16 bits: half for the test start, half for the test success.
Since we alredy have more than 16 POST tests defined and more could
be defined, this may result in an overflow and the post_output_backlog
would not work for the tests defined further of these 16 positions.

An additional field is added to global data so that we can now support up
to 32 (depending of architecture) tests. The post_log_word is only used
to record the start of the test and the new field post_log_res for the
test success (or failure). The post_output_backlog is for this change
also adapted.

      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.
