I want to create a section in RAM, allocate a specific size and place it an an address? Is it possible to do all these operations without passing a linker script "file" or w/o modifying the existing linker script ?
.myspace :
{
. = 0x10000;
. = . + STACK_SIZE;
} > ram
Is it possible to do all the operation done by linker script in command line with GNU LD/GCC ?

Description. The ld command, also called the linkage editor or binder, combines object files, archives, and import files into one output object file, resolving external references. It produces an executable object file that can be run.
The ld command language is a collection of statements; some are simple keywords setting a particular option, some are used to select and group input files or name output files; and two statement types have a fundamental and pervasive impact on the linking process.
An LD file is a script written in the GNU "linker command language." It contains one or more commands that are used to configure how input files storing static object code are to be compiled into a single executable program or library for the GNU operating system.
Seems like a way outdated answer, but anyway.
It's not possible to reserve the section size via ld command line options, but if the next section starts at the end of your special section, you can try something like this:
ld --section-start=.myspace=0x10000 -Ttext=0x11000 ...
