If anyone has any objections, please let me know. ------------------ From: James Hogan commit 55fe6da9efba102866e2fb5b40b04b6a4b26c19e upstream. cmd_dt_S_dtb constructs the assembly source to incorporate a devicetree FDT (that is, the .dtb file) as binary data in the kernel image. This assembly source contains labels before and after the binary data. The label names incorporate the file name of the corresponding .dtb file. Hyphens are not legal characters in labels, so .dtb files built into the kernel with hyphens in the file name result in errors like the following: bcm3368-netgear-cvg834g.dtb.S: Assembler messages: bcm3368-netgear-cvg834g.dtb.S:5: Error: : no such section bcm3368-netgear-cvg834g.dtb.S:5: Error: junk at end of line, first unrecognized character is `-' bcm3368-netgear-cvg834g.dtb.S:6: Error: unrecognized opcode `__dtb_bcm3368-netgear-cvg834g_begin:' bcm3368-netgear-cvg834g.dtb.S:8: Error: unrecognized opcode `__dtb_bcm3368-netgear-cvg834g_end:' bcm3368-netgear-cvg834g.dtb.S:9: Error: : no such section bcm3368-netgear-cvg834g.dtb.S:9: Error: junk at end of line, first unrecognized character is `-' Fix this by updating cmd_dt_S_dtb to transform all hyphens from the file name to underscores when constructing the labels. As of v4.16-rc2, 1139 .dts files across ARM64, ARM, MIPS and PowerPC contain hyphens in their names, but the issue only currently manifests on Broadcom MIPS platforms, as that is the only place where such files are built into the kernel. For example when CONFIG_DT_NETGEAR_CVG834G=y, or on BMIPS kernels when the dtbs target is used (in the latter case it admittedly shouldn't really build all the dtb.o files, but thats a separate issue).
