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.
