Subject: [U-Boot] [PATCH 5/5] arm: zynq: Add mini u-boot configuration for zynq
Date: Mon,  6 Nov 2017 12:45:24 +0100	[thread overview]
Message-ID: <84311726fce72c709302d88e2266f38fc912427c.1509968715.git.michal.simek@xilinx.com> (raw)
In-Reply-To: <9b2db68acd42db1a6886232e23d26b7713451eff.1509968715.git.michal.simek@xilinx.com>

Add configuration files/dtses for mini u-boot configurations which runs
out of OCM.

ram top is calculated from 0 that's why +#define CONFIG_SYS_SDRAM_BASE
0xfffc0000
+#define CONFIG_SYS_SDRAM_SIZE  0x40000
was hardcoded.
