From b6c9cc306af4e4ee401cc5f4ff1a534b067b3b20 Mon Sep 17 00:00:00 2001 From: Jamin Lin Date: Thu, 13 Apr 2023 18:31:08 +0800 Subject: kernel-fitimage: support 64 bits address The default value of address-cells is "1", so the generated "its" file only supports 32bits address for kernel FIT image. However, some platforms may want to support 64bits address of UBOOT_LOADADDRESS and UBOOT_ENTRYPOINT. Therefore, adds a variable to support both 64bits and 32bits address cells. 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: 8ce15c76c50d5d61524fea585d19989baefb5df2) Signed-off-by: Jamin Lin Signed-off-by: Luca Ceresoli Signed-off-by: Richard Purdie --- meta/classes-recipe/kernel-fitimage.bbclass | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) (limited to 'meta/classes-recipe/kernel-fitimage.bbclass') diff --git a/meta/classes-recipe/kernel-fitimage.bbclass b/meta/classes-recipe/kernel-fitimage.bbclass index 6684478c33..f1c46a453c 100644 --- a/meta/classes-recipe/kernel-fitimage.bbclass +++ b/meta/classes-recipe/kernel-fitimage.bbclass @@ -92,6 +92,10 @@ FIT_SUPPORTED_INITRAMFS_FSTYPES ?= "cpio.lz4 cpio.lzo cpio.lzma cpio.xz cpio.zst # Allow user to select the default DTB for FIT image when multiple dtb's exists.
