You will also look at the Linux kernel as well-designed software, which gives us insights into software design in general that are easily scalable yet fundamentally strong and safe. By the end of this book, you will have considerable understanding of and appreciation for the Linux kernel.
Style and approach Each chapter begins with the basic conceptual know-how for a subsystem and extends into the details of its implementation. We use appropriate code excerpts of critical routines and data structures for subsystems.

In practice, the bootloader can still be pretty complex. The bootloader has stripped-down drivers for the onboard storage, perhaps a couple of other peripherals, and just enough code to read the kernel into memory and start executing it. With the right tools, you have no reason to be afraid of modifying the bootloader — it is a program like any other.
I should mention the Boot ROM here. The Boot ROM is a small chunk of code embedded in the processor, provided by the manufacturer. This allows you to connect a brand-new, unprogrammed system to a computer over USB and run code, or flash a storage medium.
Different manufacturers call this mode different things. Allwinner calls it FEL mode. You will generally need a special program on your workstation to use this mode, and capabilities vary between different processors.
You already know what Linux is, I hope! Linux must be ported to each architecture, each part, and each board. Download e-Book.
