docs: bootconfig: Add how to use bootconfig for kernel parameters

2021-09-08T19:10:41+00:00

Add a section to describe how to use the bootconfig for specifying kernel and init parameters. This is an important section because it is the reason why this document is under the admin-guide.

docs: bootconfig: Add the endianness of fields

2020-12-01T04:22:11+00:00

Add a description about the endianness of the size and the checksum fields. Those must be stored as le32 instead of u32. This will allow us to apply bootconfig to the cross build initrd without caring the endianness.

bootconfig: Add append value operator support

2020-02-21T14:59:39+00:00

Add append value operator "+=" support to bootconfig syntax. With this operator, user can add new value to the key as an entry of array instead of overwriting. For example, foo = bar ... foo += baz Then the key "foo" has "bar" and "baz" values as an array.

bootconfig: Prohibit re-defining value on same key

2020-02-21T14:59:19+00:00

Currently, bootconfig adds a new value on the existing key to the tail of an array. But this looks a bit confusing because an admin can easily rewrite the original value in the same config file. This rejects the following value re-definition. key = value1 ... key = value2 You should rewrite value1 to value2 in this case.
