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.

The isdram command prints out decoded information the "serial presence
detect" (SPD) chip on the SDRAM SIMMs. This can be very helpful when
debugging memory configuration problems.

The ECC POST reported intermittent failures running after power-up on
the Korat PPC440EPx board. Even when the test passed, the debugging
output occasionally reported additional unexpected ECC errors.
This refactoring has three main objectives: (1) minimize the code
executed with ECC enabled during the tests, (2) add more checking of the
results so any unexpected ECC errors would cause the test to fail, and
(3) use synchronization (only) where required by the processor.

This patch extends the number of supported UECs to 4. Note that the
problem of QE thread resources exhaustion is resolved by setting the
correct number of QE threads according to Ethernet type (GBE or FE).

Now that bit 29 is the USB PHY reset bit, update the Kilauea port
to remove the USB PHY reset after powerup. The CPLD will keep the
USB PHY in reset (active low) until the bit is set to 1 in
board_early_init_f().

With recent toolchain versions, some boards would not build because
or errors like this one (here for ocotea board when building with
ELDK 4.2 beta):
ppc_4xx-ld: section .bootpg [fffff000 -> fffff23b] overlaps section .bss [fffee900 -> fffff8ab]
For many boards, the .bss section is big enough that it wraps around
at the end of the address space (0xFFFFFFFF), so the problem will not
be visible unless you use a 64 bit tool chain for development. On
some boards however, changes to the code size (due to different
optimizations) we bail out with section overlaps like above.
The fix is to add the NOLOAD attribute to the .bss and .sbss
sections, telling the linker that .bss does not consume any space in
the image.
