The boot ROM in the A10 or A20 can read the next stage of the boot code from an SD card, on-board NAND, SPI-connected memory or USB. There is no code capable of reading data from SATA, so the answer to you question is no.

To complete , the code read on the SD/NAND is used to set the system (driver to the sata for instance).
If you want to boot from your sata, you must add code in the SD/NAND to initialize the sata hd and then jump to the hd.
It might be not very easy at first sight.
