-----Original Message----- From: U-Boot u-boot-bounces@lists.denx.de On Behalf Of Alison Wang Sent: Thursday, April 23, 2020 8:08 PM To: u-boot@lists.denx.de; Priyanka Jain priyanka.jain@nxp.com; Jagdish Gediya jagdish.gediya@nxp.com Cc: Shengzhou Liu shengzhou.liu@nxp.com Subject: [PATCH v2] configs: ls1021a: Append CMA configuration to bootargs
The default reserved memory for CMA is high memory. If LPAE is enabled, highmem pages are non-remapped and can not be used with dma_alloc_coherent. Reserving low memory for CMA is needed for LS1021A. This patch appends the related CMA configuration to bootargs.
