Hi Anand,
I tried a few sdcards on the OC2 with your 2 patches.
Like with the libretech-cc, sdr104 at 200Mhz works "mostly", but, with some
sdcards, it does not - please see below. The same sdcards appear to be working
fine on my laptop.
This is something I have not been able to crack yet on the libretech-cc.
I'd suggest dropping sdr104 and keeping the max frequency at 100Mhz until we can
figure out the problem here.

Thank for your testing, I will also do some more testing on all the
sdcard and share you the result..
Mean while Sandisk Ultra microSDHC UHS-I card @A1 32GB shows.
On my Odroid C2:
[ 1.165784] meson-gx-mmc d0074000.mmc: allocated mmc-pwrseq
[ 1.403756] meson-gx-mmc d0072000.mmc: Got CD GPIO
[ 1.456160] Waiting for root device /dev/mmcblk1p2...
[ 1.608180] mmc1: new ultra high speed SDR104 SDHC card at address aaaa
[ 1.610002] mmcblk1: mmc1:aaaa JULIE 29.7 GiB
[ 1.617811] mmcblk1: p1 p2
Also I did not encounter and read/write failure on the sdcard but I
will re-test them.

Thank for your testing, I will also do some more testing on all the
sdcard and share you the result..
Mean while Sandisk Ultra microSDHC UHS-I card @A1 32GB shows.
On my Odroid C2:
[ 1.165784] meson-gx-mmc d0074000.mmc: allocated mmc-pwrseq
[ 1.403756] meson-gx-mmc d0072000.mmc: Got CD GPIO
[ 1.456160] Waiting for root device /dev/mmcblk1p2...
[ 1.608180] mmc1: new ultra high speed SDR104 SDHC card at address aaaa
[ 1.610002] mmcblk1: mmc1:aaaa JULIE 29.7 GiB
[ 1.617811] mmcblk1: p1 p2
Also I did not encounter and read/write failure on the sdcard but I
will re-test them.
