Florent Kermarrec 85a059bf77 bios/sdram: add some margin on cdly ideal_delay, do the read_leveling even if write_leveling is not optimal.
We need to provide enough information to ease support and understand the issue. The write leveling/read leveling
are doing there best to calibrate the DRAM correctly and memtest gives the final result.
