2018-10-09sandbox: Add a way to write data to the host filesystemSimon Glass
For debugging it is sometimes useful to write out data for inspection using an external tool. Add a function which can write this data to a given file. Signed-off-by: Simon Glass <sjg@chromium.org>

2018-10-08sandbox: Unprotect DATA regions in bus testsSimon Glass
On my Ubuntu 18.04.1 machine two driver-model bus tests have started failing recently. The problem appears to be that the DATA region of the executable is protected. This does not seem correct, but perhaps there is a reason. To work around it, unprotect the regions in these tests before accessing them. Signed-off-by: Simon Glass <sjg@chromium.org>

2018-09-23sandbox: Allow to execute from RAMAlexander Graf
With efi_loader, we may want to execute payloads from RAM. By default, permissions on the RAM region don't allow us to execute from there though. So let's change the default allocation scheme for RAM to also allow execution from it. That way payloads that live in U-Boot RAM can be directly executed.

2018-09-23sandbox: Fix setjmp/longjmpAlexander Graf
In sandbox, longjmp returns to itself in an endless loop because os_longjmp() calls into longjmp() which is provided by U-Boot which again calls os_longjmp(). Setjmp on the other hand must not return because otherwise the return freees up stack elements that we need during longjmp(). The only straight forward fix that doesn't involve nasty hacks I could find is to directly link against the system setjmp/longjmp implementations. That means we just provide the compiler with hints that the symbol will be available and actually fill them out with versions from libc. This approach should be reasonably platform agnostic Signed-off-by: Alexander Graf <agraf@suse.de> Reviewed-by: Simon Glass <sjg@chromium.org> Signed-off-by: Alexander Graf <agraf@suse.de>
2018-09-23sandbox: Enhance map_to_sysmem() to handle foreign pointersSimon Glass
At present map_sysmem() maps an address into the sandbox RAM buffer, return a pointer, while map_to_sysmem() goes the other way. The mapping is currently just 1:1 since a case was not found where a more flexible mapping was needed. PCI does have a separate and more complex mapping, but uses its own mechanism. However this arrange cannot handle one important case, which is where a test declares a stack variable and passes a pointer to it into a U-Boot function which uses map_to_sysmem() to turn it into a address. Since the pointer is not inside emulated DRAM, this will fail. Add a mapping feature which can handle any such pointer, mapping it to a simple tag value which can be passed around in U-Boot as an address.

2018-09-23sandbox: Add support for calling abort()Simon Glass
This function is useful to signal that the application needs to exit immediate. It can be caught with a debugger (e.g. gdb). Add a stub for it so that it can be called from within sandbox when an internal error occurs. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Alexander Graf <agraf@suse.de>
2018-09-23sandbox: Align RAM buffer to the machine page sizeSimon Glass
At present the sandbox RAM buffer is not aligned to any particular address boundary. This makes the internal pointers somewhat random with respect to the associated RAM buffer addresses. Align the buffer to the page size of the machine to help with this. Note that there is a header at the start of the allocated pointer. To avoid returning a pointer which is not aligned to a page boundary, we waste almost an entire page of memory for each allocation.

2018-09-10arch: types.h: factor out fixed width typedefs to int-ll64.hMasahiro Yamada
All architectures have the same definition for s8/16/32/64 and u8/16/32/64. Factor out the duplicated code into <asm-generic/int-ll64.h>. BTW, Linux unified the kernel space definition into int-ll64.h a few years ago as you see in Linux commit 0c79a8e29b5f ("asm/types.h: Remove include/asm-generic/int-l64.h").

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.

2018-08-21cmd: Add bind/unbind commands to bind a device to a driver from the command lineJean-Jacques Hiblot
In some cases it can be useful to be able to bind a device to a driver from the command line. The obvious example is for versatile devices such as USB gadget. Another use case is when the devices are not yet ready at startup and require some setup before the drivers are bound (ex: FPGA which bitsream is fetched from a mass storage or ethernet) usage example: bind usb_dev_generic 0 usb_ether unbind usb_dev_generic 0 usb_ether or unbind eth 1 bind /ocp/omap_dwc3@48380000/usb@48390000 usb_ether unbind /ocp/omap_dwc3@48380000/usb@48390000 Signed-off-by: Jean-Jacques Hiblot <jjhiblot@ti.com>
2018-08-20sandbox: Move BSS after EFI sectionsAlexander Graf
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 <agraf@suse.de>

2018-07-25efi_loader: Rename sections to allow for implicit dataAlexander Graf
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@suse.de> [agraf: Fix x86_64 breakage]
