ContributorCyclone V SoC custom board preloader boot sdram test issue
Dear Intel FAE and ALL,
This is Brian and having issue on maximum 2GB DDR3 boot sanity test.
There is a warning like these:
"SDRAM: Running EMIF Diagnostic Test ...Iteration 1734:, expect 0x20a69210 from address 0x20a69213, read 0x20a69210 insteadFailed"
But w/o the SDRAM test on preloader, the system can boot into distro and passed memtester.
Do the preloader have any bug on the memory size of the SDRAM?
It do show a 2048M size message.
memtester log:
```
brian@brian:~$ sudo memtester 1900M
