RE: [PATCH v2 00/10] Add SDUC Support

[Ricky WU <ricky_wu@realtek.com>]

Hi Avri,

I tested this SDUC patch for Realtek card readers and it works  


> Ultra Capacity SD cards (SDUC) was already introduced in SD7.0.  Those cards
> support capacity larger than 2TB and up to including 128TB. Thus, the address
> range of the card expands beyond the 32-bit command argument. To that end,
> a new command - CMD22 is defined, to carry the extra 6-bit upper part of the
> 38-bit block address that enable access to 128TB memory space.
> 
> SDUC capacity is agnostic to the interface mode: UHS-I and UHS-II – Same as
> SDXC.
> 
> The spec defines several extensions/modifications to the current SDXC cards,
> which we address in patches 1 - 10.  Otherwise requirements are out-of-scope
> of this change.  Specifically, CMDQ (CMD44+CMD45), and Extension for
> Video Speed Class (CMD20).
