I have a custom board of AGFB027R25AR0. I want to bring it up, now I follow the article below and encounter the following problems:

Note: (1) A "RC" labeled branch is for internal active development use and customer early access without official customer support. (2) Latest stable branch (no RC labeled) is strongly recommended for development and production use outside of Intel. (3) See README for Quartus and Device support.

Version Info：
- Quartus: 22.04
- u-boot: socfpga_v2022.10
- ATF: socfpga_v2.10.0
- Board: boot from QSPI(256M GIGADEVICE), no emmc, 1GB SDRAM(I don’t know why it can’t read 3GB SDRAM??? If I change it to 3GB in dtb, I will failed in sdram_mmr_init_full->
gd->ram_size > hw_size->‘DDR: Error: DRAM size from device tree is greater than hardware size.’) - Memory Layout: follow the attached.
