Commit 3f353ceccbbb ("vf610: refactor DDRMC code") changed on-die
termination (ODT) values from 120 Ohm to 60 Ohm and enabled a static
read/write leveling which has not been tested with this board. This
commit reverts both changes and makes sure that memory gets
initialized as it has been done before the mentioned commit.

arm: Round the dma_alloc_coherent memory size to cache line aligned

When running usb dwc3 gadget driver, we meet random USB enumeration failure in fastboot.
The root cause is a cache coherence issue. When it happens, the ctrl_req in
gadget driver is allocated at 0xfe932f40, and the usb_composite_dev (cdev)
is allocated at 0xfe932f60. So after we submit the setup request (cache flushed) to USB
controller, any accessing to usb_composite_dev variable will cause the cache line refill, then
when setup transfer is completed, reading the setup data in ctrl_req will gets old value from
cache not from memory.

The ctrl_req is allocated by API dma_alloc_coherent, but u-boot don't have cohernet memory.
so it still needs cache maintain operations before/after HW accessing. Since the cache flush or
invalidate bases on cache line, so when the allocated memory size is not cache line aligned,
potentially it may meet such issue.

This patch modifies the dma_alloc_coherent API to round the size to cache line aligned.

and we are now setting SDRAM_MAX_SIZE as max available space for

pico-imx7d: Increase the CONFIG_ENV_OFFSET size

U-Boot binary has grown in such a way that it goes beyond the reserved
area for the environment variables.

Running "saveenv" causes U-Boot to hang because of this overlap.

Fix this problem by increasing the CONFIG_ENV_OFFSET size.

Also, in order to prevent this same problem in the future, use
CONFIG_BOARD_SIZE_LIMIT, which will detect the overlap in build-time.

CONFIG_BOARD_SIZE_LIMIT does not accept math expressions, so declare
CONFIG_ENV_OFFSET with its direct value instead.

5 years agopcm058: fix NAND flash not using badblock table
Harald Seiler [Fri, 7 Dec 2018 09:19:36 +0000 (10:19 +0100)]
pcm058: fix NAND flash not using badblock table

Currently, U-Boot ignores the BBT stored in the last 4 blocks of NAND
flash because the NAND_BBT_USE_FLASH flag is not set.  This leads to
two issues:

* U-Boot silently uses a memory-only BBT which is initialized with all
  blocks marked as good.  This means, actual bad blocks are marked good
  and U-Boot might try writing to or reading from them.
* The BBT in flash, which will be created once Linux boots up, is not
  off limits for a driver ontop, like UBI.  While it does not seem to
  consistently produce an error, sometimes UBI will fail to attach
  because the BBT blocks obviously don't contain valid UBI data.

To fix this, this patch sets the CONFIG_SYS_NAND_USE_FLASH_BBT option,
which is used in ./drivers/mtd/nand/raw/mxs_nand.c to decide whether
a BBT in flash is used.
