Subject: [PATCH] tools: zynqmpbif: Add support for load=after
|
|
|
|
Some times it's handy to have a partition loaded immediately after
|
|
the end of the previous blob. The most obvious example for this is
|
|
a U-Boot binary (coming from .elf) and a device tree file.
|
|
|
|
This patch adds that logic. With this, the following bif snippet
|
|
does what you would expect:
|
|
|
|
[destination_cpu=a5x-0, exception_level=el-2] u-boot.elf
|
|
[load=after] u-boot.dtb
|
|
|
|
converts to
|
|
|
|
FSBL payload on CPU a5x-0 (PS):
|
|
Offset : 0x00590500
|
|
Size : 577768 (0x8d0e8) bytes
|
|
Load : 0x08000000
|
|
Attributes : EL2
|
|
Checksum : 0xefca2cad
|
|
FSBL payload on CPU none (PS):
|
|
Offset : 0x0061d640
|
|
Size : 129760 (0x1fae0) bytes
|
|
Load : 0x0808d0e8 (entry=0x00000000)
|
|
Attributes : EL3
|
|
Checksum : 0xf7dd3d49
