* ARM: layerscape: ppa: fix error propagation in ppa_init()Ahmad Fatoum2020-07-141-4/+3
| | | | | | | | On fit_open_image, we returned PTR_ERR(fit) instead of the correct ret. We also didn't call fit_close as we should. Fix this. Signed-off-by: Ahmad Fatoum <a.fatoum@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* sandbox: specify sizeof(dma_addr_t) == sizeof(phys_addr_t) == 8 on 64BITAhmad Fatoum2020-07-143-7/+5
| | | | | | | | | | | | | sizeof(dma_addr_t) == 8 shouldn't introduce any functional change, because we can't have DMA on sandbox. For now it suppresses benign warnings about mismatched pointer and integer sizes when some headers are included. sizeof(phys_addr_t) == 8 was already the case on systems with __x86_64__. As CONFIG_64BIT now is set according to the bitness of the compiler, we can migrate this fully to Kconfig.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If gcc supports multiple architectures, barebox uses only the default when compiling for ARCH=sandbox, this is e.g. the case with compilers that generate both 32- and 64-bit x86 executables. There can be good reasons to force 32-bit though, e.g. to reduce memory consumption while fuzzing or to temporarily avoid 32-to-64-bit warnings, while running the static analyzer.

The thin archive is basically a text file that only contains paths to object files. As Linux commit 98ced886dd79 mentioned, this has a lot of benefits: - save disk space for builds - speed-up building a little - fix some issues when liking a giant executable (for example, allyesconfig on ARM Linux) - work better with dead code elimination The last one is important for barebox because pbl highly relies on the dead code elimination (-f{function,data}-sections and --gc-sections) dropping symbols that are unreachable from the linker's entry point. The dead code elimination does not work if the same symbol names are used in the pevious incremental link mechanism because the same name symbols all go into the same section. Commit a83c97f2a406 ("ARM: socfpga: generate smaller images when multiple boards are selected") worked around it by giving a dedicate section to each of the same name symbols. This workaround can go away. built-in.o was renamed to built-in.a since it is now an archive. built-in-pbl.o was renamed to built-in.pbl.a for consistency.

The purposes of doing so were: [1] prevent GNU Make from deleting the intermediate files [2] include .*.cmd files In contrast, Linux does not use a special syntax for embedding DTBs into the kernel. For example, as you see in arch/sh/boot/dts/Makefile of Linux 5.6, obj-y += <basename>.dtb.o ... just works. This is because scripts/Kbuild.include specifies .SECONDARY to cater to [1], and scripts/Makefile.build adds the intermediates to 'targets' to deal with [2]. Barebox had already imported the same code from Linux, so you can use obj-y instead of obj-dtb-y, like Linux. pbl-dtb-y and lwl-dtb-y are barebox-specific cases, so I added the %.dtb.pbl.o pattern to intermediate_targets.
