The default value of address-cells is "1", so the generated "its" file only support 32bits address for uboot FIT image. However, some platforms may want to support 64bits address of UBOOT_LOADADDRESS and UBOOT_ENTRYPOINT. Therefore, add variables to support both 64bits and 32bits address. By default, the address-cell is 1 which is used for 32bits load address. If users would like to use 64bits load address, users are able to set as following for "0x400000000" 64bits load address. 1. FIT_ADDRESS_CELLS = "2" 2. UBOOT_LOADADDRESS= "0x04 0x00000000" (From OE-Core rev: b4e46cdbd0727d97d13c2b8e9e4ce19c5c693f51) Signed-off-by: Jamin Lin <jamin_lin@aspeedtech.com> Signed-off-by: Luca Ceresoli <luca.ceresoli@bootlin.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
