2010-04-07fsl-ddr: Fix the turnaround timing for TIMING_CFG_4Dave Liu
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. Signed-off-by: Dave Liu <daveliu@freescale.com>
2010-04-07fsl_esdhc: Only modify the field we are changing in WMLRoy Zang
When we set the read or write watermark in WML we should maintain the rest of the register as is, rather than using some hard coded value. Signed-off-by: Roy Zang <tie-fei.zang@freescale.com> Acked-by: Stefano Babic <sbabic@denx.de> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2010-04-07fsl_esdhc: Add function to reset the eSDHC controllerJerry Huang
To support multiple block read command we must set abort or use auto CMD12. If we booted from eSDHC controller neither of these are used and thus we need to reset the controller to allow multiple block read to function.

2010-04-03Nomadik: fix reset_timer()Alessandro Rubini
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).

2010-04-02nios2: Reload timer count in reset_timer()Scott McNutt
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. Signed-off-by: Scott McNutt <smcnutt@psyent.com>

2010-03-30mpc86xx: set the DDR BATs after calculating true DDR sizeTimur Tabi
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.
