#1268 STM32H742xI/G STM32H743x SD via SPI is affected by ES0392 Rev 9 2.14.1 Spurious DMA Rx Transaction

[Andrey B]

Some H7 have silicon defect ES0392 Rev 9 2.14.1 Spurious DMA Rx Transaction which is observable while using SD card via SPI

suggesting a work-around see https://github.com/rusefi/ChibiOS/commit/3a54b0bcbfa6c7712f61d8e6520627dde926152f.patch

[Andrey B]

this is only needed in case of https://sourceforge.net/p/chibios/bugs/1270/

[Giovanni Di Sirio]

This is the wrong place where to put this fix: It is H7-specific and this file is a portable one.

This should go eventually into the SPI LLD driver, upper layers should not see things like this.
