Partially revert "efi_loader: Rename sections to allow for implicit data"

2018-08-23T20:17:41Z

This partially reverts commit 7e21fbca26d18327cf7cabaad08df276a06a07d8. That change broke sandbox EFI support for unknown reasons. It also changes sandbox to use--gc-sections which we don't want. For now I am just reverting the sandbox portion as presumably this change is safe on other architectures.

sandbox: Move BSS after EFI sections

2018-08-20T09:39:19Z

Something went wrong when writing the sandbox linker scripts and so we ended up with a .bss section marker right before the efi runtime sections. That obviously is a terrible idea, as it may result in overwriting efi runtime code and data. So let's move the .bss identifier behind the efi sections. Signed-off-by: Alexander Graf

Patch queue for efi - 2018-07-25 Highlights this time: - Many small fixes to improve spec compatibility (found by SCT) - Almost enough to run with sandbox target - GetTime() improvements - Enable EFI_LOADER and HYP entry on ARMv7 with NONSEC=y

sandbox: eth-raw: Add a SIMPLE_BUS to enumerate host interfaces

2018-07-26T19:08:19Z

Ask the OS for each of its interfaces and for each one, bind a U-Boot device and then probe it. This will allocate the priv data structure that is then populated. Signed-off-by: Joe Hershberger Reviewed-by: Simon Glass

sandbox: eth-raw: Allow interface to be specified by index

2018-07-26T19:08:18Z

With systemd stable interface names, eth0 will almost never exist. Instead of using that name in the sandbox.dts, use an index. Signed-off-by: Joe Hershberger Reviewed-by: Simon Glass

sandbox: eth-raw: Add a function to ask the host about localhost

2018-07-26T19:08:18Z

Instead of doing a simple string compare against "lo", look for the flag that indicates a localhost interface. Signed-off-by: Joe Hershberger Reviewed-by: Simon Glass

sandbox: eth-raw: Make sure descriptors are always initialized

2018-07-26T19:08:17Z

If we let descriptors equal 0, we can end up closing STDIN. Make sure they start out as -1. Signed-off-by: Joe Hershberger Reviewed-by: Simon Glass

sandbox: eth-raw: Correct valid socket test in send/recv

2018-07-26T19:08:17Z

In open, the socket is correctly checked to be -1 in the error case. In send and recv, we checked for 0, but that is a valid socket number. Correct this by checking for -1 as a bad socket everywhere. Signed-off-by: Joe Hershberger Reviewed-by: Simon Glass

efi_loader: Rename sections to allow for implicit data

2018-07-25T12:57:44Z

Some times gcc may generate data that is then used within code that may be part of an efi runtime section. That data could be jump tables, constants or strings. In order to make sure we catch these, we need to ensure that gcc emits them into a section that we can relocate together with all the other efi runtime bits. This only works if the -ffunction-sections and -fdata-sections flags are passed and the efi runtime functions are in a section that starts with ".text". Up to now we had all efi runtime bits in sections that did not interfere with the normal section naming scheme, but this forces us to do so. Hence we need to move the efi_loader text/data/rodata sections before the global *(.text*) catch-all section. With this patch in place, we should hopefully have an easier time to extend the efi runtime functionality in the future. Signed-off-by: Alexander Graf [agraf: Fix x86_64 breakage]
