QSPI Flash vs SD-Card - HPS flash memory

Hi! :)

QSPI is very-very small in comparison with mechanic insertable cards.

In devices, ready for users, may be minimum jingles and contacts generally.

When Altera makes kit, its target was show many possibilityes of many components.

And so be need BSEL jumpers for show a boot from different sources.

In typical to-market device is only one boot source, HPS may boot from address 00000000.

If need be many boots, BSEL may point to many addresses as 10000000, 20000000, ...F0000000 and like this: flash devices always may be readed directly on system bus.

Then don't need BootROM, Preloader and other complex stadies with 64K-limitation with Release and without sources, big applications may start from flash with interval 1-4-16-128M, init all, include SDRAM, copy self there and run in one stady! Freedom is best, and same freedomical States not love this ! :)
