These changes were identified by HighSmith Bill ,Mazzyar and Joseph for
DDR configuration in u-boot code. Some are related to performance, some
affect stability and some correct few basic errors in the current
configuration.
The changes have been tested and found to give better memory latency
figures on MPC8313eRDB.LMBench figures prove it.
The changes are:
- CS0_CONFIG[ AP_n_EN] is changed from 1 to 0
(this may improve performance for application with many read
or write to open pages).
- CS0_CONFIG[ODT_WR_CFG] is currently changed from 100 to
001 (activating all the CS when only one is used may cause
unwanted noise on the system)
- TIMING_CFG_1[ACTTOPRE] is changed from 9clks to 8clks (based on
Tras=45ns)
- TIMING_CFG_1[REFREC] changed from 21 clks to 18clks.
- TIMING_CFG_2[AL] value changed from 0 setting to 1 clk to
comply with the 3 ODT clk requirements)
- TIMING_CFG_2[CPO] was set to a reserved value, changed to RL+3/4.
- TIMING_CFG_2[FOUR_ACT] is changed from 10 clks to 6clks.
- DDR_SDRAM_MODE[AL]changed from 0 to 1.
- DDR_SDRAM_MODE[WRREC] changed from 1 clk to 3 clks.
- DDR_SDRAM_INTERVAL[REFINT] is changed from 0x0320 to 0x0510.
- DDR_SDRAM_INTERVAL[BSTOPRE] is changed from 0x64 to 0x0500.

This patch makes two additions to GPIO support:
First, it adds function gpio_read_in_bit() to read the a bit from the
GPIO Input Register (GPIOx_IR) in the same way that function
gpio_read_out_bit() reads a bit from the GPIO Output Register
(GPIOx_OR).
Second, it modifies function gpio_set_chip_configuration() to provide
an additional option for configuring the GPIO from the
"CFG_4xx_GPIO_TABLE".
According to the 440EPx User's Manual, when an alternate output is used,
the three-state control is configured in one of two ways, depending on
the particular output. The first option is to select the corresponding
alternate three-state control in the GPIOx_TRSH/L registers. The second
option is to select the GPIO Three-State Control Register (GPIOx_TCR) in
the GPIOx_TRSH/L registers, and set the corresponding bit in the
GPIOx_TCR register to enable the output. For example, the Manual
specifies configuring the GPIO00 Alternate 1 Signal (PreAddr07) to use
the alternate three-state control (first option), and specifies
configuring the GPIO32 Alternate 1 Signal (USB2OM0) with the output
enabled in the GPIOx_TCR register (second option).
Currently, gpio_set_chip_configuration() configures all alternate signal
outputs to use the first option. This patch allow the second option to
be selected by setting the "out_val" element in the table entry to
"GPIO_OUT_1". The first option is used when the "out_val" element is
set to "GPIO_OUT_0". Because "out_val" is not currently used when an
alternate signal is selected, and because all current GPIO tables set
"out_val" to "GPIO_OUT_0" for all alternate signals, this patch should
not change any existing configurations.

map_physmem() returns a virtual address which can be used to access a

This patch adds a stub implementation which simply returns the
physical address cast to a uchar * for all architectures except AVR32,
which converts the physical address to an uncached virtual mapping.
unmap_physmem() is a no-op on all architectures, but if any

In the future the offsets to various blocks may not be in same location.
Move to using CFG_MPC85xx_CPM_ADDR as the base of the CPM registers
instead of getting it via &immap->im_cpm.

* Removed HAS_ETH2/HAS_ETH3 - MPC8544 only has TSEC1/2
* Removed some misc environment setup
* Moved to using fdtfile & fdtaddr as fdt env var names
* Enabled CONFIG_CMDLINE_EDITING

The following patch adds support for non-CFI flash ROMS, by hooking into the
CFI flash code and using most of its code, as recently discussed here in the
thread "Mixing CFI and non-CFI flashs".

This patch enables the hardware-fix for the PCI/DMA errata's 19+22 by
setting the FIXD bit in the SDR0_MFR register. Here a description of the
symptoms:
Problem Description
------------------------------
If a DMA is performed between memory and PCI with the DMA 1 Controller
using prefetch, and as a result uses a special purpose buffer selected by
the PCIXn Bridge Options 1 Register (PCIXn_BRDGOPT1[RBP7] - bits 31-29),
the first part of the transfer sequence is performed twice. The
PPC440SPe PCI Controller requests more data than was needed such that in
the case of enforce memory protection, a host CPU exception can occur.
No data is corrupted, because data transfer is stopped in the PCI
Controller. Prefetch enable is specified by setting DMA Configuration
Register (I2O0_DMAx_CFG[DXEPD] - bit 31) to 0.
Behavior that may be observed in a running system
---------------------------------------------------------------------------
1. DMA performance is decreased because of the double access on the PCI bus
interface.
2. If an illegal access to some address on the PCI bus is detected at the
system level, a machine check or similar system error may occur.
Workarounds Available
----------------------------------
1. Do not program prefetch. Note that a prefetch command cannot be programmed
without selecting a special purpose buffer.
2. To avoid crossing a physical boundary of the PCI slave device, add 512
bytes of address to the PCI address range.

Added the following fdt fixup helpers:
* do_fixup_by_prop{_u32} - Find matching nodes by property name/value
* do_fixup_by_compat{_u32} - Find matching nodes by compat
The _u32 variants work the same only the property they are setting
is know to be a 32-bit integer instead of a byte buffer.

Moved the generic fixup handling code out of cpu/mpc5xxx and cpu/mpc8260
into common/fdt_support.c and renamed:
do_fixup() -> do_fixup_by_path()
do_fixup_u32() -> do_fixup_by_path_u32()

Removed:
fdt_node_is_compatible
fdt_find_node_by_type
fdt_find_compatible_node
To ease merge of newer libfdt as we aren't using them anywhere at this time.
Also moved fdt_find_and_setprop out of libfdt into fdt_support.c for the same
reason.
