-----Original Message----- From: U-Boot u-boot-bounces@lists.denx.de On Behalf Of Meenakshi Aggarwal Sent: Wednesday, February 20, 2019 3:36 PM To: u-boot@lists.denx.de Subject: [U-Boot] [PATCH v1] mc : Add support to run MC in 128 MB DDR size
Ashish: Rephrase to "Reduce MC memory size to 128M" from the above it sound like system DDR is 128MB
Regards Ashish
ls2088, ls1088 : minimum DDR size for MC is 128 MB lx2 : minimum DDR size for MC is 256 MB
