Re: [U-Boot] [PATCH] net: fec: Avoid MX28 bus sync issue

Dear Robert Hodaszi,

In message 5232F2E7.4050407@digi.com you wrote:

Ok. Then what about if I would use the stack, but align the buffer manually.

Has this been tested? Does it work?

•   uchar buff[FEC_MAX_PKT_SIZE] __aligned(ARCH_DMA_MINALIGN);
  

•   /* Align the receive buffer */
  

•   uchar buff_unaligned[FEC_MAX_PKT_SIZE + (ARCH_DMA_MINALIGN - 1)];
  

•   uchar *buff = ((uint32_t)buff_unaligned + (ARCH_DMA_MINALIGN - 1)) & ~(ARCH_DMA_MINALIGN - 1);
  

You should use the ALIGN() macro here.

Best regards,

Wolfgang Denk
