AM5728: SDIO question

Part Number: AM5728

About AM5728 SDIO problem, please help confirm it, the AM5728 TRM wrote:

Does the “full Compliance” mentioned above mean all the MMCIs? Are there any restrictions on the rate and mode of operation of these interfaces (MMCi)?

Bsides, I also have 3 question:

  1. We need a SDIO 4bit, high-speed rate, which MMC port can be recommended?
  2. We need a EMMC as fast as possible, which MMC port must be used? And how fast can it reach?
  3. What is the maximum SDIO clock rate for AM437x and AM335x?
