In general any DRAM address, that isn't overwritten during a boot is suitable for pstore.
Range from 0x40000000 - 0x50000000 is heavily used by u-boot for internal use and to load kernel, fdt, fdto, scripts, pxefile and ramdisk later in the boot process. Ramdisk start address is 0x4FF00000, initramfs for kernel with some hacking features and debug info enabled can take more than 100Mb and final address will be around 0x58000000. Address 0x61000000 will most likely not overlap with that.
