[U-Boot] Question about mem parameter in the bootargs

Hi, Does someone knows what is the smallest step to increase the mem parameter in the bootargs? I am dealing with an embedded system based on an ARM LPC3250 and running linux. I have a very critical memory constraint and I would like to have mem=3584k instead mem=3M or mem=4M. The Linux boot up

[U-Boot] Question about PCIe configuration

Hi, I am trying to map a PCIe peripherical on my MPC8536 custom board. I already have u-boot and linux kernel running fine on this board. The peripherical is on PCIe1 port. Compiling u-boot using debug flag I have the following log: pci_init_board: devdisr=40900, sdrs2_io_sel=7, io_sel=7

[U-Boot] U-boot issue with Intel StrataFlash P30.

Hi, I am porting the u-boot to a MPC8536E custom board and I am facing an issue with flash. When u-boot tries to detect the flash (INTEL STRATAFLASH P30) it just freeze. The u-boot is started from the same flash. The problem happen when the CFI Driver tries a read from flash (flash_read8()) for

[U-Boot] MPC8536 custom board without SPD EEPROM configured DDR

Hi, I am facing some issues porting u-boot to a MPC8536 custom board. My custom board doesn't implement SPD EEPROM to configure ddr, so I must setup ddr manually. I am starting from MPC8536ds target. This board uses a SPD EEPROM to configure the ddr controler. So, I undefined CONFIG_SPD_EEPROM an
