Forty-Bot: thanks. I am on 5.4. Curious to where the 0x800000 address is coming from. Grepping the source tree for Linux and/or u-boot yeilds nothing
<Forty-Bot>
probably from CONFIG_SYS_LOAD_ADDR
<Forty-Bot>
but idk why it's that and not the bottom of ram
<Forty-Bot>
ask monstr if he ever gets on
<ac_slater>
Forty-Bot: ah! So confusing. In the xilinx u-boot fork, CONFIG_SYS_LOAD_ADDR is 0x0800.0000 but the some u-boot env vars in that same file (include/configs/xilinx_zynqmp.h) show kernel_addr=0x80.0000
<ac_slater>
guess I have to find out what CONFIG_SYS_LOAD_ADDR does...
<Forty-Bot>
it's the default value for $loadaddr
<Forty-Bot>
e.g. where stuff goes if you don't specify an address
<Forty-Bot>
and if they aren't equal that means I misread the number of zeros :P
<ac_slater>
;) yea I put the separator. They are not equal
<ac_slater>
the thing that's tripping me up, is Linux has text_offset in the Image header as 0x0800.0000.0000
<ac_slater>
so many different offsets floating around. Not sure if I should understand my board's memory layout, Linux's layout/boot stuff, or what u-boot is trying to do
<ac_slater>
(text_offset in the Linux header reads as "Image load offset")

The linux arm64 booting page has this nugget "... Where image_size is zero, text_offset can be assumed to be 0x80000."
<ac_slater>
which matches Xilinx's kernel_addr address.
<ac_slater>
(in u-boot)
<ac_slater>
arrrggg so confusing
<ac_slater>
I guess I don't know the significance of Linux's text_offset
<ac_slater>
Forty-Bot: I do see the reference to text_offset getting removed in >5.8

I sent a patch to the uboot mailing list (I think correctly) but have not had any responses
<MartijnBraam[m]>
except "Awaits moderator approval"

MartijnBraam[m]: had the same, but i think the patch eventually made it through. helps to be registered to the list even if you have emails turned off per listserv settings
