Revise the value of return value of flash_get_page_size()

TomoYamanaka · TomoYamanaka · commit cb087ed63ab1 · 2018-09-29T05:22:37.000+09:00
Currently the return value of flash_get_page_size() is 1 since the min size per one writing is 1 byte by Flash spec.
However, I noticed that this value causes a enormous write time When writing large data such as FW update.
So I revised this value to 8 byte by considering the writing time, memory alignment and memory hole.
