Subject: [PATCH 9/9] memtest: add rewritten memtest command
Date: Sun, 13 Jan 2013 18:42:23 +0100	[thread overview]
Message-ID: <1358098943-18928-10-git-send-email-alex.aring@gmail.com> (raw)
In-Reply-To: <1358098943-18928-1-git-send-email-alex.aring@gmail.com>

Rewrite memtest command:
	- Skip barebox sdram regions.
	- Uncache unused mem regions while testing.
	- Add iteration parameter.
	- Add parameter to do only bus testing.
	- Check start and end addresses.
	- Testing all banks if no start and end
	  address are given.

	- Add sha changes (thanks):
	- fix calculation of regions to test. When we use PAGE_ALIGN on
	  size, size can be to high.
	  - start address has to be aligned up
	  - end address has to be aligned down
	  - then size can be calculated as end - start + 1
	- Add ctrlc() to the longer loops
	- Add a progress bar to give some visual feedback that something
	  issues
	  still going on.

	- Change to use end element instead of size in region struct.
	- Fix some newline issues.

	- Add '-c' parameter if CONFIG_MMU enabled
	  to test with enabled cache.
	- Fix some size calculation.
	- set start address to 0xffffffff

+	 *              address and checking for aliasing.
+	 *              This test will find single-bit
+	 *              address failures such as stuck -high,
+	 *              stuck-low, and shorted pins. The base

+	 *              selected by the caller.
+	 *
+	 * Notes:	For best results, the selected base
+	 *              address should have enough LSB 0's to
+	 *              guarantee single address bit changes.
+	 *              For example, to test a 64-Kbyte
+	 *              region, select a base address on a
+	 *              64-Kbyte boundary. Also, select the

+	 *              all possible.
+	 *
+	 * ## NOTE ##	Be sure to specify start and end
+	 *              addresses such that num_words has
+	 *              lots of bits set. For example an
+	 *              address range of 01000000 02000000 is
+	 *              bad while a range of 01000000
