uclinux/Makefile

The toplevel Makefile is modified slightly to incorporate the changes in the building of the romfs image. The uClinux Make process proceeds as follows:

subdirs: User libraries (uclinux/lib/) are built, followed by selected user applications (uclinux/user).
romfs: The user applications are installed in the romfs directory (uclinux/romfs).
modules: Linux kernel modules are compiled.
modules_install: The compiled kernel modules are copied to the romfs directory (uclinux/romfs/lib/modules/).
image: The romfs image is generated at (uclinux/linux-2.4.x/romfs.o) from the romfs directory.
linux: The static components of the linux kernel are compiled to create the linux elf image (uclinux/linux-2.4.x/linux). The romfs image is included in the linux elf image, at the location specified by the linker script.
images: The final ARM7 binary is created.

uclinux/vendors/ACME/SOHO-B0X/Makefile

This is the vendor specific Makefile used to build the rom filesystem structure, generate the romfs image and create the linux binary.

romfs: The directory structure for the rom filesystem is created here. ROMFS_DIRS specifies the directories that are to be created, and DEVICES specifies the device files for various device drivers. The device files are of the format: DEVICE_NAME,character/block device,major number,minor number. Additionally a number of symbolic links are created and essential files copied to their respective locations in the romfs directory.
image: The romfs binary is created using the utilities genromfs and arm-elf-ld. The three commented commands concatenate the romfs binary at the end of the linux binary instead of within it.
images: The linux binary is created using arm-elf-ld and copied to the tftp download location.
