Expansion to nand flash driver

[sabdulqadir]

This expansion helps support higher density devices which have multiple
dies, logical units and planes on top of the standard block and page
structures of standard nand flash ICs.

• Included stm32f723xx targets
• Bug fix (STM32_NAND_USE_NAND1)
• changed map_cmd and map_addr to 8 bits in struct NANDDriver
• Bug fix (dmaStreamAlloc returns dma_stream_t)
• DSB assembly instruction added for fixing issues with M7 processor
• added nand_lld_read_id() function

Hi,
This is regarding the bug I reported earlier (Bug in hal_fsmc.h #227).
I also included the changes I did to expand the driver to make it work with devices with higher densities (die, logical units and planes). For simpler devices, these can be defined as 1 for the sake of expansion.

I see some build tests have failed and ill work my way through them.
Let me know what you guys think about the changes.

Thanks,
AQ

Hi, did you have time to look at the build error?
Thanks

Hi Fabian,
Not just yet, I am busy with some deliverables.
Ill hopefully get it done by end of this month, unless you tell me it's more urgent.

Thanks,

it's not urgent, there are just some examples in testhal to update since you changed the nand function declarations.
I'll merge it and fix the examples. Thanks!

Thanks Fabien for the help.
Appreciate it.
