[U-Boot] Brotli Compression to Fit Image/bzImage

[vinoth eswaran]

Hello,

 I am working on an embedded project using Minnowboard Max with U-boot
and customised Linux kernel.

To optimize boot time, currently I am comparing the different
comparison algorithms and have read about Brotli compression, which
seems to be good. So I have planned to test and see how good is Brotli
compression for my use case? The current Linux kernel and U-boot
doesn't support this compression, so I have to add this compression
algorithm code.

I am seeing two ways of doing this,

1. In U-Boot

Fit Image creation from vmlinux. Adding Brotli compression to mkimage
tool and decompressor to U-Boot.
Here we are using mkimage tool to create the image.fit. I can do some
changes in mkimage and add the decompressor to the U-boot code

2. In Linux Kernel

bzImage --> adding the Brotli compression and decompression to Linux Kernel

and change the default compression from gzip to brotli in the Linux
kernel Configuration.

I don't know which way is comparably easier to implement, any
suggestions on these topic will be of great help. Have any body tried
this algorithm for the Linux Kernel??
