+
+/* Memory test
+ *
+ * General observations:
+ * o The recommended test sequence is to test the data lines: if they are
+ * broken, nothing else will work properly. Then test the address
+ * lines. Finally, test the cells in the memory now that the test
+ * program knows that the address and data lines work properly.
+ * This sequence also helps isolate and identify what is faulty.
+ *
+ * o For the address line test, it is a good idea to use the base
+ * address of the lowest memory location, which causes a '1' bit to
+ * walk through a field of zeros on the address lines and the highest
+ * memory location, which causes a '0' bit to walk through a field of
+ * '1's on the address line.
+ *
+ * o Floating buses can fool memory tests if the test routine writes
+ * a value and then reads it back immediately. The problem is, the
+ * write will charge the residual capacitance on the data bus so the
+ * bus retains its state briefely. When the test program reads the
+ * value back immediately, the capacitance of the bus can allow it
+ * to read back what was written, even though the memory circuitry
+ * is broken. To avoid this, the test program should write a test
+ * pattern to the target location, write a different pattern elsewhere
+ * to charge the residual capacitance in a differnt manner, then read
+ * the target location back.
+ *
+ * o Always read the target location EXACTLY ONCE and save it in a local
+ * variable. The problem with reading the target location more than
+ * once is that the second and subsequent reads may work properly,
+ * resulting in a failed test that tells the poor technician that
+ * "Memory error at 00000000, wrote aaaaaaaa, read aaaaaaaa" which
+ * doesn't help him one bit and causes puzzled phone calls. Been there,
+ * done that.
+ *
+ * Data line test:
+ * ---------------
+ * This tests data lines for shorts and opens by forcing adjacent data
+ * to opposite states. Because the data lines could be routed in an
+ * arbitrary manner the must ensure test patterns ensure that every case
+ * is tested. By using the following series of binary patterns every
+ * combination of adjacent bits is test regardless of routing.
+ *
+ * ...101010101010101010101010
+ * ...110011001100110011001100
+ * ...111100001111000011110000
+ * ...111111110000000011111111
+ *
+ * Carrying this out, gives us six hex patterns as follows:
+ *
+ * 0xaaaaaaaaaaaaaaaa
+ * 0xcccccccccccccccc
+ * 0xf0f0f0f0f0f0f0f0
+ * 0xff00ff00ff00ff00
+ * 0xffff0000ffff0000
+ * 0xffffffff00000000
+ *
+ * To test for short and opens to other signals on our boards, we
+ * simply test with the 1's complemnt of the paterns as well, resulting
+ * in twelve patterns total.
+ *
+ * After writing a test pattern. a special pattern 0x0123456789ABCDEF is
+ * written to a different address in case the data lines are floating.
+ * Thus, if a byte lane fails, you will see part of the special
+ * pattern in that byte lane when the test runs. For example, if the
+ * xx__xxxxxxxxxxxx byte line fails, you will see aa23aaaaaaaaaaaa
+ * (for the 'a' test pattern).
+ *
+ * Address line test:
+ * ------------------
+ * This function performs a test to verify that all the address lines
+ * hooked up to the RAM work properly. If there is an address line
+ * fault, it usually shows up as two different locations in the address
+ * map (related by the faulty address line) mapping to one physical
+ * memory storage location. The artifact that shows up is writing to
+ * the first location "changes" the second location.
+ *
+ * To test all address lines, we start with the given base address and
+ * xor the address with a '1' bit to flip one address line. For each
+ * test, we shift the '1' bit left to test the next address line.
+ *
+ * In the actual code, we start with address sizeof(ulong) since our
+ * test pattern we use is a ulong and thus, if we tried to test lower
+ * order address bits, it wouldn't work because our pattern would
+ * overwrite itself.
+ *
+ * Example for a 4 bit address space with the base at 0000:
+ * 0000 <- base
+ * 0001 <- test 1
+ * 0010 <- test 2
+ * 0100 <- test 3
+ * 1000 <- test 4
+ * Example for a 4 bit address space with the base at 0010:
+ * 0010 <- base
+ * 0011 <- test 1
+ * 0000 <- (below the base address, skipped)
+ * 0110 <- test 2
+ * 1010 <- test 3
+ *
+ * The test locations are successively tested to make sure that they are
+ * not "mirrored" onto the base address due to a faulty address line.
+ * Note that the base and each test location are related by one address
+ * line flipped. Note that the base address need not be all zeros.
+ *
+ * Memory tests 1-4:
+ * -----------------
+ * These tests verify RAM using sequential writes and reads
+ * to/from RAM. There are several test cases that use different patterns to
+ * verify RAM. Each test case fills a region of RAM with one pattern and
+ * then reads the region back and compares its contents with the pattern.
+ * The following patterns are used:
+ *
+ * 1a) zero pattern (0x00000000)
+ * 1b) negative pattern (0xffffffff)
+ * 1c) checkerboard pattern (0x55555555)
+ * 1d) checkerboard pattern (0xaaaaaaaa)
+ * 2) bit-flip pattern ((1 << (offset % 32))
+ * 3) address pattern (offset)
+ * 4) address pattern (~offset)
+ *
+ * Being run in normal mode, the test verifies only small 4Kb
+ * regions of RAM around each 1Mb boundary. For example, for 64Mb
+ * RAM the following areas are verified: 0x00000000-0x00000800,
+ * 0x000ff800-0x00100800, 0x001ff800-0x00200800, ..., 0x03fff800-
+ * 0x04000000. If the test is run in slow-test mode, it verifies
+ * the whole RAM.
