SDK 2.0: Customize u-boot

Hello,

According to QorIQ-SDK-2.0-1609-IC-Rev1.pdf, page 69, in order to change u-boot code:

3. $ cd <S>

Note: Use bitbake -e <package-name> | grep ^S= to get value of <S>, the package source code
directory.

I do not understand. What is <S> ?

Thank you,

Z.V

<S> is a pseudo-variable that receives the value of a string produced by the following pipe:

bitbake -e <package-name> | grep ^S=

Below is how it works on my machine:

$ bitbake -e u-boot | grep ^S=
S="/home/platon/private/ltib/QorIQ-SDK-V2.0-20160527-yocto/build_ls1043ardb/tmp/work/ls1043ardb-fsl-linux/u-boot-qoriq/2016.01+fslgit-r0/git"

$ cd /home/platon/private/ltib/QorIQ-SDK-V2.0-20160527-yocto/build_ls1043ardb/tmp/work/ls1043ardb-fsl-linux/u-boot-qoriq/2016.01+fslgit-r0/git

$ ls
api    common     disk     dts       include  lib                ls1043ardb_nand_config    MAKEALL   post     snapshot.commit
