9 years agosunxi: Fix buggy sun6i/sun8i DRAM size detection logic

sunxi: Fix buggy sun6i/sun8i DRAM size detection logic

After reboot, reset or even short power off, DRAM typically retains
the old stale data for some period of time (for this type of memory,
the bits of data are stored in slowly discharging capacitors).

The current sun6i/sun8i DRAM size detection logic, which is
inherited from the Allwinner code, relies on using a large magic
signature with the hope that it is unique enough and unlikely to
ever accidentally match this leftover garbage data in RAM. But
this approach is inherently unsafe, as can be demonstrated using
the following test program:

/***** A testcase for reproducing the problem ******/

void main(int argc, char *argv[])
{
    size_t size, i;
    uint32_t *buf;
    /* Allocate the buffer */
    if (argc < 2 || !(size = (size_t)atoi(argv[1]) * 1048576) ||
                    !(buf = malloc(size))) {
        printf("Need buffer size in MiB as a cmdline argument\n");
        exit(1);
    }
    /* Fill it with the Allwinner DRAM "magic" values */
    for (i = 0; i < size / 4; i++)
        buf[i] = 0xaa55aa55 + ((uintptr_t)&buf[i] / 4) % 64;
    /* Try to reboot */
    system("reboot");
    /* And wait */
    for (;;) {}
}
/***************************************************/

If this test program is run on the device (giving it a large
chunk of memory), then the DRAM size detection logic in u-boot
gets confused after reboot and fails to initialize DRAM properly.

A better approach is not to rely on luck and abstain from making
any assumptions about the properties of the leftover garbage
data in RAM. Instead just use a more reliable code for testing
whether two different addresses refer to the same memory location.

sunxi: mmc: Properly setup mod-clk and clock sampling phases

The sunxi mmc controller has both an internal clock divider, as well as
the divider in the mod0-clk for the mmc controller.

The internal divider cannot be used, as it conflicts with the setting of
clock sampling phases which is done in the mod0-clk, so it must be set to
0 (divide by 1).

For some reason while the kernel has had this correct from day one, the
u-boot sunxi mmc code has been using a fixed mod0-clk and setting its
internal divider depending on the desired speed. This is something which
we've inherited from the original Allwinner u-boot sources, but while this
has been fixed in Allwinner's own u-boot code at least for the A23 and later
upstream u-boot was still doing this wrong.
