ec145e87b8 fsl-ddr: Fix the turnaround timing for TIMING_CFG_4
Read-to-read/Write-to-write turnaround for same chip select
of DDR3 memory, BL/2+2 cycles is enough for them at BC4 and
OTF case, BL/2 cycles is enough for fixed BL8.
Cutting down the turnaround from BL/2+4 to BL/2+2 or BL/2
will improve the memory performance.

48bb3bb5ac fsl_esdhc: Add function to reset the eSDHC controller

4b894a97d3 Nomadik: fix reset_timer()
Previous code was failing when reading back the timer less than
400us after resetting it. This lead nand operations to incorrectly
timeout any now and then.  Moreover, writing the load register isn't
immediately reflected in the value register. We must wait for a clock
edge, so read_timer now waits for the value to change at least once,
otherwise nand operation would timeout anyways (though less frequently).

d8bc0a2889 nios2: Reload timer count in reset_timer()
When the timestamp is incremented via interrupt and the interrupt
   period is greater than 1 msec, successive calls to get_timer() can
   produce inaccurate timing since the interrupts are asynchronous
   to the timing loop. For example, with an interrupt period of 10 msec
   two successive calls to get_timer() could indicate an elapsed time
   of 10 msec after only several hundred usecs -- depending on when
   the next interrupt actually occurs. This behavior can cause
   reliability issues with components such as CFI and NAND.

   This can be remedied by calling reset_timer() prior to establishing
   the base timestamp with get_timer(0), provided reset_timer()
   resets the hardware timer (rather than simply resetting only the
   timestamp). This has the effect of synchronizing the interrupts
   (and the advance of the timestamp) with the timing loop.

9ff32d8ccf mpc86xx: set the DDR BATs after calculating true DDR size
After determining how much DDR is actually in the system, set DBAT0 and
IBAT0 accordingly.  This ensures that the CPU won't attempt to access
(via speculation) addresses outside of actual memory.

On 86xx systems, DBAT0 and IBAT0 (the BATs for DDR) are initialized to 2GB
and kept that way.  If the system has less than 2GB of memory (typical for
an MPC8610 HPCD), the CPU may attempt to access this memory during
speculation.  The zlib code is notorious for generating such memory reads,
and indeed on the MPC8610, uncompressing the Linux kernel causes a machine
check (without this patch).

Currently we are limited to power of two sized DDR since we only use a
single bat.  If a non-power of two size is used that is less than
CONFIG_MAX_MEM_MAPPED u-boot will crash.
